Author Sara van Os is a Mexican-American, self-professed decomposition nerd who has, since college, been working in hospitality while diligently collecting stories of decidedly peculiar goings-on in the workplace. Her debut novel, Decomposition Book, arrives on May 7, 2026, via Dead Ink Books in the UK, and on May 19, 2026, via Hanover Square Press, and is guaranteed to thoroughly gast your flabbers.
The novel follows Savannah, who, after an emotionally ruinous falling-out with her best friend, retreats to her family’s isolated lake house, where she unravels in solitude. When she wakes in the woods beside a dead woman for reasons unknown, she discovers a journal that pulls her into the victim Ava’s final, harrowing days.
As Savannah becomes inexorably obsessed with Ava’s story, she begins to sense her presence—and forms a bond that feels at once terrifying and strangely alluringly real. Soon, Savannah is forced to confront whether she’s losing her marbles or clutching at the only meaningful connection she has left in the world.
To celebrate the book’s release, CinemaChords sat down with van Os, who discussed how she arrived at the novel’s unique format, one that does not flinch from its necrotic premise yet wriggles with pitch-black humour and delivers heart-wrenching insights into loneliness, grief, and the surprising ways people reach for connection when life knocks them sideways. We also got into how the novel serves as a more-than-welcome reminder of the power of the written word: how stories allow readers to inhabit other lives, draw strength from them, and ultimately form bonds in ways we least expect.
