ABOUT I Know What You Did

When a bestselling novel fictionalizes the death of her childhood best friend—and accuses her of the murder—Petal Woznewski must figure out who wrote it and why. Truth and fiction collide in this captivating debut novel by Cayce Osborne.

Petal Woznewski is content with her quiet, introverted life in New York City: she has her junk food, her movies, and her on-again, off-again boyfriend, Gus. That peace is shattered when her name appears on the dedication page of an anonymously written thriller with a cryptic note: “I know what you did, Petal Woznewski. And now everyone else will, too.”

As she reads, Petal realizes the story is rooted in a secret she buried thirty years earlier, when she was fourteen. A secret involving the tragic death of her friend, Megan. A secret that only one other person knows—their old friend, Jenny. Armed with a copy of the book and her own suspicions, Petal returns to her hometown of Madison, Wisconsin. There, she discovers more questions than answers. Jenny has disappeared, and Petal’s old high school crush, Ben, doesn’t know anything about the book—at least not anything he’s telling.

As sinister clues pile up, and the thriller’s plot detours dangerously from the facts, Petal has no choice but to confront her past and solve the mystery of who wrote it—before her very real life ends as tragically as the novel.


“A psychological thriller with a beating pulse. I was pulled into Petal’s story right from the start. Gripping, atmospheric and sharp, this fresh, new voice is written with a wry humor. A must read.”
— Christina McDonald,
USA Today bestselling author

“A whip-smart and thoroughly engaging psychological thriller, with a highly memorable protagonist and a brilliantly original narrative concept. I raced through I Know What You Did in a matter of days and found it a brilliantly fresh voice in the psychological thriller genre.”
​ — Philippa East, author of I’ll Never Tell

I Know What You Did is a fast-paced thriller that grips you from the opening lines and doesn't let go until the dramatic conclusion.”
​ — Stephanie DeCarolis,
author of Deadly Little Lies

“Propulsive and electric, I Know What You Did will have you by the throat from the very first chapter.”
​ —Mindy Carlson, author of Her Dying Day
