About this book

Book Summary

An emotional, electrifying, and darkly hilarious debut about a woman who finds a dead body and can't give up its ghost, for fans of Mona Awad, Yellowjackets, and weird girl fiction.

Spiraling from a disastrous falling-out with her best friend, Savannah retreats to her parents' empty lake house in upstate New York to tend her wounds. Isolated and reeling from rejection, she spends her days in a fog, drinking and overthinking in equal worrisome measure. Until she wakes up one morning in the woods behind the house—next to a dead body.

Instead of calling the police, Savannah reads the journal she finds nearby, reliving the last desperate months of this woman's life lost in the wilderness, fighting for survival. Ava, as it turns out, is more than just a cold, lonely corpse. She was funny. She was smart. And Savannah has finally found someone she can talk to…

As she pushes deeper into Ava's harrowing story, Savannah notices a change, a shift in her reality. Each page brings her closer to the Ava from the journal…and the ghost before her now. Before long, Savannah feels something for Ava she hasn't felt for anyone else—and there's a good chance letting go would haunt her for the rest of her life.

Is Savannah finally losing her grip? Or has she found the friend she's needed all along?

Media Reviews

"Fans of Yellowjackets will eat up this queer, psychologically chaotic tale. A decadently bizarre novel for fans of queer survival stories." —Kirkus Reviews (starred review)

"In spite of their grim circumstances, the characters are endearing, their queer relationships characterized by overwhelming compassion and leavened by a gentle dark humor. This is sure to win van Os many fans." —Publishers Weekly

"Gripping and inventive, Decomposition Book confronts what it is possible to endure for love." —Booklist

"Intense, irreverent, surprising, raw. I relished every minute of Sara van Os's debut and—heart in mouth—will be coming back for more." —Natalia Theodoridou, author of Sour Cherry

"Told with delicious humor and surprising grace, Decomposition Book is a compulsively readable story of courage, of desire, of unrelenting love, and of what is left when one's humanity is stripped away—whether by loss, obsession, or rot. A marvelously strange novel, both unprecedented and unforgettable." —Kerry Cullen, author of House of Beth
