Plot Summary
Bodies, Banter, and Barriers
Tanrian Marshal Hart Ralston and undertaker Mercy Birdsall's relationship is defined by sharp banter and mutual irritation. Hart, a demigod haunted by loneliness, regularly delivers bodies to Birdsall & Son, where Mercy manages the family business after her mother's death. Their interactions are laced with sarcasm and unspoken longing, each hiding wounds and vulnerabilities. The world they inhabit is one where death is both business and ritual, and the borderlands of Tanria are plagued by drudges—reanimated corpses infected by lost souls. The story's tone is set by their antagonism, the weight of duty, and the isolation that comes from living among the dead. Yet, beneath the surface, both yearn for connection, even as they push each other away.
Letters Across the Void
After a particularly bruising encounter, Hart pours his loneliness into a letter addressed to "a friend" and drops it in a magical nimkilim mailbox, not expecting a reply. To his surprise, Mercy receives the letter, recognizing a kindred spirit in the anonymous writer's vulnerability. She responds, and a secret correspondence begins, each letter a lifeline. Through these letters, they share their fears, hopes, and frustrations, revealing more of themselves than they ever could in person. The anonymity allows honesty and intimacy to blossom, even as neither knows the other's identity. Their written words become a refuge from the burdens of their daily lives, and the emotional stakes quietly rise as their connection deepens.
Apprentices and Animosity
Hart is forced to take on a young apprentice, Penrose Duckers, whose optimism and naivete contrast sharply with Hart's cynicism. Meanwhile, Mercy's family life unravels: her brother Zeddie confesses he never trained as an undertaker, threatening the future of Birdsall & Son. The business's survival is further imperiled by rival undertaker Cunningham's predatory tactics. Both Hart and Mercy are beset by responsibilities and disappointments, their public personas hardening even as their private letters grow more tender. The tension between their outward hostility and secret yearning intensifies, setting the stage for transformation.
Family Secrets Unveiled
Mercy's family is at a crossroads. Zeddie's confession that he wants to be a chef, not an undertaker, devastates Mercy, who has sacrificed her own dreams for the family business. Lilian, her sister, reveals she's pregnant and plans to leave the business as well. Mercy is left to shoulder the burden alone, her sense of duty clashing with her desire for a life of her own. Meanwhile, Hart's strained relationship with his former partner Alma and his unresolved grief over his mentor Bill's death haunt him. Both protagonists are trapped by the expectations of others and the ghosts of their pasts, their only solace found in the anonymous letters that have become their emotional anchor.
Anonymous Connections Deepen
The correspondence between Hart and Mercy grows more intimate, each letter peeling back layers of armor. They share secrets, regrets, and small joys, finding in each other the understanding and acceptance missing from their daily lives. The letters become a space where they can be vulnerable, funny, and hopeful. Both begin to suspect the other's identity, but fear of disappointment keeps them from seeking the truth. Their emotional connection becomes the most real thing in their lives, even as the world around them grows more dangerous and uncertain.
Confessions and Consequences
The pressure of secrets mounts. Mercy's family confronts her about the mysterious letters, and Zeddie's departure from the business becomes inevitable. Cunningham's machinations escalate, threatening to destroy Birdsall & Son. Hart and Mercy's real-world interactions remain fraught, but their letters brim with longing and the ache of unspoken love. When they finally agree to meet, the revelation of their true identities is both a shock and a heartbreak, as years of misunderstanding and pride come crashing down. The fallout is painful, forcing both to confront the consequences of their choices and the cost of vulnerability.
Drudges and Dangers
Tanria's drudge problem worsens, with more bodies and greater risks for marshals and undertakers alike. Hart and Duckers face increasing peril, their partnership tested by violence and fear. Mercy, overwhelmed by the influx of corpses and the collapse of her family's business, clings to her sense of purpose even as hope dwindles. The world grows darker, and the threat of annihilation—personal and communal—looms. Yet, even in the face of death, the possibility of redemption flickers, sustained by the memory of connection and the hope for something more.
Rivalries and Revelations
Mercy uncovers Cunningham's scheme: he's using his patented embalming patch to smuggle bodies with intact appendixes into Tanria, fueling the drudge epidemic and profiting from the government's indigent processing grant. With Lilian's help, Mercy gathers evidence and allies, determined to save her family's legacy and protect the border towns. The confrontation with Cunningham is tense and dangerous, but Mercy's courage and ingenuity prevail. The victory is bittersweet, as the cost of survival is measured in exhaustion, loss, and the knowledge that some wounds cannot be healed by justice alone.
Hearts Laid Bare
Hart and Mercy's relationship reaches a breaking point. The truth about their letters and feelings comes to light, but the revelation is marred by anger, betrayal, and grief. Hart, believing he has lost everything, throws himself into a final, desperate act: he returns to the heart of Tanria to open the door to the House of the Unknown God, hoping to end the drudge plague once and for all. The act is both sacrifice and penance, a culmination of his lifelong struggle with mortality, guilt, and the longing for home. Mercy, left behind, must face the possibility of a world without him.
Dancing with Death
Hart's journey into Tanria is harrowing and mythic. Battling drudges and his own wounds, he reaches the door to the House of the Unknown God, using his mother's key to open it. The lost souls of Tanria are finally set free, and Hart's body succumbs to death. In the liminal space between worlds, he confronts the Warden—his divine father—and finds a measure of peace and understanding. The moment is both an ending and a beginning, as Hart's sacrifice brings salvation to the living but costs him his life.
Letters Become Love
Mercy, devastated by Hart's death, prepares his body with tenderness and sorrow. As she mourns, a final letter from Hart reaches her, a confession of love and regret that breaks her heart anew. Yet, in the midst of grief, a miracle occurs: Hart's demigod nature grants him a second life. He awakens in Mercy's care, bewildered and vulnerable, and the two finally confront the truth of their feelings. Forgiveness and love triumph over pain and pride, and the possibility of a shared future emerges from the ashes of loss.
Truths, Trials, and Trust
With the drudge threat ended and Cunningham brought to justice, Mercy and Hart begin to rebuild their lives and their relationship. Mercy inherits Hart's estate, securing the future of Birdsall & Son and her own independence. The family business is reborn, and the wounds of the past begin to heal. Hart, no longer haunted by the fear of immortality or the burden of guilt, embraces his place in the world and the love he shares with Mercy. Together, they learn to trust in themselves and each other, finding joy in the ordinary and the extraordinary alike.
Sacrifice and Salvation
The story's emotional climax is not just Hart's sacrifice, but the willingness of both protagonists to risk everything for each other and their community. Love is shown to be an act of courage, requiring honesty, vulnerability, and the acceptance of imperfection. The supernatural elements—gods, souls, and the afterlife—underscore the human truths at the heart of the tale: that to love is to risk loss, and to live fully is to embrace both sorrow and joy. The ending is both a celebration and a benediction, as Hart and Mercy, surrounded by family and friends, dance together in the light of a world remade by their choices.
Death, Grief, and Grace
The aftermath of Hart's death and resurrection is marked by grief, gratitude, and grace. Mercy's mourning is raw and real, but her love endures, sustained by memory and hope. Hart's return is a gift, but it does not erase the pain of loss or the scars of the past. Together, they honor the dead, cherish the living, and find meaning in the rituals that bind them to each other and their community. The story affirms that grace is found not in perfection, but in the willingness to forgive, to begin again, and to love without reservation.
Homecoming and Healing
Hart and Mercy's reunion is mirrored by the healing of their families and the restoration of Birdsall & Son. Old wounds are acknowledged and tended, and new bonds are forged. The community, once threatened by death and division, is renewed by acts of courage, kindness, and solidarity. The supernatural fades into the background, leaving the characters to face the future with hope and humility. The home they create together is not just a place, but a promise: that love, in all its messiness and wonder, is worth the risk.
Love Beyond the End
In the story's final moments, Hart and Mercy, surrounded by family, friends, and the living and the dead, embrace the fullness of life. Their love, tested by adversity and loss, endures and flourishes. The world is not perfect, but it is enough.

The story closes with laughter, music, and the promise of many tomorrows, as Hart and Mercy, at last, undertake the journey of life together.
Analysis
Megan Bannen's The Undertaking of Hart and Mercy is a luminous exploration of love, loss, and the human need for connection, set against a fantastical backdrop where death is both business and mystery. The novel's genius lies in its ability to balance whimsy and gravity, using the supernatural to illuminate the most ordinary—and profound—truths of the human heart. Through the dual narrative of Hart and Mercy, Bannen examines how grief, duty, and pride can isolate us, and how vulnerability, honesty, and forgiveness can heal even the deepest wounds. The anonymous letters at the story's core are a metaphor for the masks we wear and the risks we take in seeking intimacy. The enemies-to-lovers arc is not just romantic, but redemptive, showing that love is an act of courage and that true connection requires the willingness to be seen, flaws and all. The novel's ultimate message is one of hope: that even in a world haunted by death and disappointment, joy is possible, and love—messy, imperfect, and hard-won—is worth every risk.
Review Summary
The Undertaking of Hart and Mercy receives an overall 4.04/5 rating, with readers praising its creative fantasy world, enemies-to-lovers romance, and charming characters. Many highlight the sweet anonymous letter correspondence reminiscent of You've Got Mail, along with memorable side characters like a foul-mouthed rabbit mailman. Common criticisms include underdeveloped worldbuilding, rushed romantic development, and overuse of miscommunication tropes. Fans particularly loved the emotional depth, unique macabre setting, and the balance of humor with heartfelt moments.

Plot Devices
Enemies-to-Lovers and Epistolary Romance
The novel's central device is the enemies-to-lovers trope, heightened by the use of anonymous letters that allow Hart and Mercy to connect in ways they cannot in person. Their public antagonism is a mask for vulnerability, and the gradual revelation of their identities is both a source of tension and catharsis. The letters serve as a confessional, a space for honesty and intimacy, and their eventual convergence with real life is the story's emotional fulcrum.
Magical Realism and World-Building
The setting blends Western, fantasy, and magical realist elements: Tanria is a land where the dead walk, gods are real, and the afterlife is a tangible destination. The rituals of death—salting, wrapping, boatmaking—are both practical and sacred, grounding the supernatural in the everyday. The world's rules are revealed through character experience, with the supernatural serving as metaphor for grief, legacy, and the search for meaning.
Parallel Character Arcs and Mirrored Relationships
Hart and Mercy's journeys mirror each other: both are isolated by duty and loss, both seek connection, and both must confront the consequences of pride and secrecy. Their relationship is echoed in the mentorship between Hart and Pen, the sibling bonds among the Birdsalls, and the romantic subplot between Pen and Zeddie. These parallels reinforce the story's themes of forgiveness, vulnerability, and the necessity of community.
Sacrifice, Redemption, and Resurrection
The narrative structure builds toward Hart's sacrificial act—opening the door to the afterlife and ending the drudge plague. His death and resurrection are both literal and symbolic, representing the possibility of redemption and the power of love to transcend even the greatest losses. The story uses foreshadowing, mythic imagery, and cyclical motifs (doors, keys, boats) to underscore the idea that endings are also beginnings.
Humor and Heartbreak
Despite its macabre setting, the novel is suffused with humor—witty banter, absurd situations, and affectionate teasing. This levity counterbalances the story's darker themes, making the moments of heartbreak more poignant and the eventual triumph of love more satisfying. The interplay of comedy and tragedy is a hallmark of the narrative voice, inviting readers to laugh, cry, and hope alongside the characters.
