Plot Summary
Lost in Familiar Halls
Joey Harker, an ordinary high schooler with a notoriously poor sense of direction, gets lost in his own house, foreshadowing the journey to come. His life is unremarkable: a loving but distracted family, a crush on Rowena, and a quirky teacher, Mr. Dimas, who values unconventional learning. When Joey's class is blindfolded and dropped around town for a social studies test, he's determined to impress Rowena by leading their group. But as he tries to navigate, Joey's confidence falters, and he becomes more lost than ever. This simple misadventure sets the stage for a much larger journey, as Joey's inability to find his way home becomes a metaphor for his impending journey across worlds, where the stakes are far higher than a failed school assignment.
Mist and Mirrors
Joey's attempt to find his way back leads him into a strange, persistent mist. When he emerges, the world is subtly but unmistakably altered: familiar landmarks are off, people don't recognize him, and even his own home is changed. His mother is different, his sister is replaced by a girl version of himself, and he's a stranger in his own life. The shock is profound—Joey realizes he's crossed into an alternate reality. The sense of dislocation is overwhelming, and the emotional impact is acute: he's lost not just in space, but in identity. This chapter marks the first true crossing of worlds, as Joey's confusion and fear are matched only by his growing sense that something extraordinary—and dangerous—is happening to him.
Stranger with My Face
Joey's confusion deepens when he's confronted by a masked stranger who looks and sounds eerily like himself. Before explanations can be given, they're attacked by mysterious agents wielding electrified nets. The stranger, Jay, urges Joey to run, revealing that Joey has unwittingly "Walked" between worlds, attracting the attention of powerful enemies. In a desperate escape, Joey's latent ability to move between realities is triggered, saving him but leaving him even more isolated. The encounter with Jay—an older, alternate version of himself—introduces the concept of the multiverse and the dangers that come with being a Walker. Joey's world is now one of shifting identities, relentless pursuit, and the dawning realization that he is both hunted and uniquely gifted.
Worlds Unravel
Seeking help, Joey turns to Mr. Dimas, only to be ensnared by Lady Indigo, a powerful sorceress from HEX, and her grotesque companions. Under her spell, Joey is compelled to follow her aboard a flying pirate ship, the Lacrimae Mundi, where he learns that Walkers like himself are harvested for their power. The emotional core here is Joey's helplessness—his will is not his own, and he's a commodity in a cosmic war. The ship's surreal journey through the Nowhere-at-All, and the chilling plans HEX has for him, drive home the stakes: Joey is no longer a lost boy, but a prize in a battle between magic and science, with his very essence at risk.
HEX and the Pirate Ship
Jay, the silver-suited alternate Joey, infiltrates the HEX ship to rescue Joey. In a tense escape, Jay reveals the truth: the multiverse is a battleground between HEX (magic) and the Binary (science), both exploiting Walkers to fuel their conquests. As they flee through the In-Between—a chaotic, surreal realm between worlds—Jay is mortally wounded saving Joey from a monstrous creature. The emotional impact is profound: Joey witnesses his own older self's death, inheriting both guilt and responsibility. Jay's final act is to entrust Joey with the knowledge and tools to find InterWorld, the organization fighting to maintain balance. The loss is deeply personal, marking Joey's transformation from victim to potential hero.
Jay's Sacrifice
Joey, devastated by Jay's death, is aided by Hue, a friendly mudluff (multidimensional life-form) he freed earlier. With Hue's help, Joey dons Jay's encounter suit and carries his body through the In-Between, determined to honor Jay's last wishes. The journey is both literal and symbolic: Joey must navigate the chaos of the multiverse and the turmoil within himself. He delivers Jay's body to InterWorld's base, where he is met with suspicion and grief. The emotional arc here is one of mourning, guilt, and the first stirrings of resolve. Joey is no longer just a lost boy—he's a survivor, carrying the weight of sacrifice and the hope of redemption.
The In-Between
At InterWorld's floating base, Joey is inducted into a society of alternate Joeys—each from a different Earth, each with unique traits. He faces resentment for Jay's death and must prove himself through grueling training in both magic and science. The base is a place of wonder and strangeness, but also of loneliness and self-doubt. Joey's struggle to fit in, to atone for past mistakes, and to master his abilities is both a coming-of-age and a test of character. The camaraderie and rivalry among the team, the bizarre curriculum, and the ever-present threat of HEX and Binary forces create a crucible in which Joey's identity is forged anew.
InterWorld Base
Joey's training intensifies, and he forms a team with other versions of himself: Jo (winged), Josef (strong), Jakon (wolfish), Jai (psychic), and J/O (cybernetic). Their first real mission is a "milk run" to retrieve beacons on a neutral world, but it quickly turns into a trap. HEX lures them into a shadow realm, capturing the team and separating Joey from his friends. The emotional stakes are high: Joey's leadership is tested, and his sense of responsibility for his team's fate deepens. The mission's failure leads to Joey's memory being wiped and his return to his original Earth, seemingly ending his journey and compounding his guilt.
Training and Teamwork
Back on his home Earth, Joey struggles with amnesia and a sense of profound loss. Fragments of his training and adventures surface in dreams and reflexes, alienating him from his family and peers. A chance encounter with a soap bubble—reminding him of Hue—triggers the return of his memories. The emotional arc is one of isolation, confusion, and the painful process of reclaiming identity. Joey's decision to return to InterWorld, despite the risk and the pain of leaving his family, marks a turning point: he chooses duty and the greater good over personal comfort, embracing his role as a Walker.
The Trap of Shadow Worlds
Joey, with Hue's help, re-enters the In-Between and discovers the truth about the shadow realm trap. He locates the portal to the HEX dreadnought, the Malefic, where his team is imprisoned and Walkers' souls are harvested as fuel. The rescue is fraught with peril: Joey must navigate the labyrinthine ship, confront monstrous enemies, and free his friends from both physical and psychological captivity. The emotional core is Joey's determination to make amends and his growing confidence as a leader. The team's reunion is bittersweet, shadowed by the horrors they've witnessed and the knowledge that the battle is far from over.
Memory Erased, Memory Returned
In the Malefic's engine room, Joey and his team discover the bottled souls of countless Walkers. Together, they shatter the jars, unleashing a storm of vengeful spirits that destroy the ship's engines and sow chaos among the HEX forces. The act is both an act of mercy and rebellion, freeing the enslaved and crippling the enemy. The team's escape is a desperate race against time, complicated by the need to rescue Hue, who has been captured by Lord Dogknife. The emotional climax is one of solidarity, sacrifice, and the realization that their greatest strength lies in their unity and compassion.
The Rescue Mission
The final showdown takes place in the collapsing Malefic. Joey bargains with Lord Dogknife for Hue's release, using empathy and the power of memory to free the trapped spirits and break the villain's hold. The escape is harrowing: the team, aided by Hue and their combined abilities, narrowly makes it through a shrinking portal as the ship is destroyed. The emotional resolution is one of triumph tempered by loss—victory comes at a cost, and the scars of battle linger. Joey's leadership is affirmed, and the team emerges stronger, bonded by shared ordeal and mutual respect.
The Malefic's Heart
Back at InterWorld, Joey and his team face the Old Man's stern debriefing. Their reckless actions are chastised, but their potential is recognized. Hue is allowed to stay, and the team is officially formed, ready to face new challenges. The emotional arc closes with a sense of belonging and purpose: Joey is no longer lost, but found—part of a family forged not by blood, but by choice and courage. The story ends with the team called to action once more, walking into the unknown, guardians of balance in an infinite multiverse.
Characters
Joey Harker
Joey is the quintessential everyman, initially defined by his lack of direction—both literal and metaphorical. His journey is one of profound transformation: from a confused, self-doubting teenager to a courageous, self-sacrificing leader. Joey's relationships—with his family, his alternate selves, and especially Jay—are marked by longing, guilt, and the search for identity. Psychologically, Joey is driven by a need to belong and to make amends for perceived failures. His empathy, resilience, and capacity for growth set him apart, allowing him to unite disparate versions of himself into a true team. By the end, Joey embodies the balance he seeks to protect: a synthesis of vulnerability and strength, individuality and unity.
Jay
Jay is an older, battle-hardened version of Joey, serving as both guide and cautionary tale. He is resourceful, brave, and deeply committed to the cause of InterWorld, but also weary and scarred by loss. Jay's relationship with Joey is complex: he is both protector and the embodiment of what Joey might become. His sacrifice is the emotional fulcrum of the story, imparting wisdom and responsibility to Joey. Psychologically, Jay represents the potential for both greatness and tragedy inherent in every choice. His death is both a loss and a legacy, propelling Joey toward maturity and purpose.
Lady Indigo
Lady Indigo is the primary antagonist from the HEX faction, wielding powerful magic and a chilling sense of entitlement. She is manipulative, charismatic, and utterly remorseless, viewing Walkers as resources to be exploited. Her relationship with Joey is predatory—she seeks to dominate and consume, both literally and figuratively. Psychologically, Lady Indigo embodies the dangers of unchecked power and the allure of surrendering will. Her presence is a constant threat, forcing Joey to confront his own vulnerabilities and the seductive nature of evil.
Lord Dogknife
Lord Dogknife is the ultimate villain, a being of immense power and malice. He is both physically and psychologically terrifying, delighting in the suffering of others and the subjugation of souls. His interactions with Joey are marked by sadism and contempt, challenging Joey's courage and resolve. Psychologically, Dogknife represents the abyss—the consequences of absolute power divorced from empathy. His defeat is not just a tactical victory, but a moral one, affirming the value of compassion and resistance.
Hue
Hue is a mudluff, a nonverbal, color-shifting creature from the In-Between. Initially a curiosity, Hue becomes a vital companion, saving Joey multiple times and symbolizing the power of kindness across boundaries. Hue's relationship with Joey is one of mutual trust and affection, transcending language and species. Psychologically, Hue represents the unexpected rewards of empathy and the importance of protecting the vulnerable. Hue's presence also catalyzes Joey's memory and growth, serving as both guide and friend.
Jo
Jo is a female, angelic version of Joey from a magic-dominated Earth. She is proud, independent, and initially distant, but gradually comes to respect and support Joey. Her wings symbolize both her difference and her potential for transcendence. Psychologically, Jo struggles with trust and vulnerability, but her loyalty to the team is unwavering. Her development mirrors Joey's, as both learn to balance individuality with collective purpose.
J/O
J/O is a childlike, part-machine Joey from a technologically advanced world. He is brilliant, brash, and sometimes abrasive, relying on logic and data over emotion. His relationship with Joey is competitive but ultimately cooperative, as both learn to value each other's strengths. Psychologically, J/O represents the dangers and benefits of technological augmentation, as well as the need for humility and connection.
Jai
Jai is a meditative, psychic Joey from a world where spiritual power is paramount. He is serene, wise, and often serves as the team's moral compass. Jai's abilities are less flashy but deeply influential, providing guidance and stability. Psychologically, Jai embodies the virtues of patience, introspection, and balance, helping the team navigate both external and internal challenges.
Josef
Josef is a massive, strong Joey from a high-gravity world. Despite his size, he is kind-hearted and often provides comic relief. His strength is both literal and metaphorical, supporting the team in moments of crisis. Psychologically, Josef grapples with being underestimated and finding his place among more "specialized" teammates, ultimately proving that heart and muscle are equally vital.
Jakon
Jakon is a lupine Joey from a world where humanity evolved alongside wolves. She is fierce, protective, and sometimes abrasive, but her loyalty to the team is unquestioned. Jakon's animal instincts and keen senses are invaluable, and her journey mirrors Joey's in learning to trust and rely on others. Psychologically, Jakon represents the wild, untamed aspects of self, and the challenge of integrating them into a cooperative whole.
Plot Devices
Multiverse and Alternate Selves
The central device is the existence of the Altiverse—a multiverse of parallel Earths, each with its own Joey Harker. This structure allows for exploration of identity, choice, and consequence, as Joey encounters versions of himself shaped by different circumstances. The narrative leverages this device to examine both the universality and uniqueness of the self, and to dramatize the stakes of the cosmic conflict between HEX (magic) and the Binary (science). The presence of alternate selves also enables themes of teamwork, empathy, and self-acceptance, as Joey learns to value both his individuality and his place in a larger whole.
The In-Between
The In-Between is a chaotic, ever-shifting realm connecting all worlds, inhabited by strange creatures like mudluffs. It serves as both a literal and metaphorical space for transformation, testing, and revelation. The In-Between's unpredictability heightens tension and underscores the instability of identity and reality. It is also the site of key plot developments—rescues, chases, and the forging of alliances—making it a crucible for character growth.
Memory and Amnesia
Joey's memory is erased after his initial failure, symbolizing both the loss of innocence and the possibility of renewal. The return of his memories, triggered by empathy and connection (with Hue), marks a rebirth and a conscious choice to embrace responsibility. This device allows for exploration of trauma, healing, and the power of self-knowledge.
Bottled Souls and Power Extraction
The HEX and Binary factions harvest Walkers' essences to power their technologies and magics, literalizing the theme of exploitation. The image of bottled souls is both a horror and a call to action, motivating Joey and his team to rebel and liberate the oppressed. This device also serves as a metaphor for the commodification of individuality and the dangers of dehumanization.
Foreshadowing and Recursion
The narrative is rich with foreshadowing—Joey's initial lostness, the recurring motif of mirrors and doubles, the cyclical nature of memory and choice. Events and symbols recur in altered forms, reinforcing the interconnectedness of all things and the possibility of change. The story's structure itself is recursive, with Joey's journey echoing Jay's, and the team's formation mirroring the process of self-integration.
Analysis
InterWorld is a vibrant, emotionally resonant exploration of identity, choice, and the struggle for balance in a chaotic universe. At its core, the novel asks what it means to be oneself in a world of infinite possibilities—and whether individuality or unity is the greater good. Through Joey's journey from lost boy to leader, the story dramatizes the pain and necessity of growth: the willingness to leave comfort behind, to face one's own failures, and to embrace the responsibilities that come with power. The multiverse setting is not just a backdrop for adventure, but a metaphor for adolescence, trauma, and the search for meaning. The conflict between HEX and the Binary, magic and science, is less about external enemies than about the dangers of extremism and the need for synthesis. InterWorld's greatest lesson is that true strength lies in empathy, cooperation, and the courage to walk into the unknown—not alone, but together. In a world where every choice creates a new reality, the only way forward is to keep walking, to keep choosing, and to keep believing in the possibility of change.

Review Summary
InterWorld receives mixed reviews, with praise for its imaginative concept of parallel worlds and dimensional travel. Readers appreciate the blend of science fiction and fantasy elements. However, some find the character development lacking and the plot simplistic for Gaiman's standards. The book is generally considered better suited for younger readers, around ages 9-12. While entertaining, it doesn't reach the heights of Gaiman's other works. The collaboration with Michael Reaves is noted, with some speculating Reaves did most of the writing.
