About this audiobook

A #1 Wall Street Journal, Amazon Charts, USA Today, and Washington Post bestseller.

#1 New York Times bestselling author Gregg Olsen’s shocking and empowering true-crime story of three sisters determined to survive their mother’s house of horrors.

After more than a decade, when sisters Nikki, Sami, and Tori Knotek hear the word mom, it claws like an eagle’s talons, triggering memories that have been their secret since childhood. Until now.

For years, behind the closed doors of their farmhouse in Raymond, Washington, their sadistic mother, Shelly, subjected her girls to unimaginable abuse, degradation, torture, and psychic terrors. Through it all, Nikki, Sami, and Tori developed a defiant bond that made them far less vulnerable than Shelly imagined. Even as others were drawn into their mother’s dark and perverse web, the sisters found the strength and courage to escape an escalating nightmare that culminated in multiple murders.

Harrowing and heartrending, If You Tell is a survivor’s story of absolute evil—and the freedom and justice that Nikki, Sami, and Tori risked their lives to fight for. Sisters forever, victims no more, they found a light in the darkness that made them the resilient women they are today—loving, loved, and moving on.

If You Tell is a heartbreaking but powerful book about abuse, survival, and sisterhood. Although some parts are extremely difficult to read, the story highlights the courage of the sisters and their determination to finally break free. I think it would appeal to anyone who enjoys true crime while also being interested in stories of survival and human resilience.

Gregg Olsen tells a truly chilling story in If You Tell. The book is filled with shocking events, but what makes it stand out is the focus on the sisters and their eventual escape from their mother's control. I was constantly wondering how the story would develop and found myself wanting to keep reading. It is a powerful example of resilience.

About the author

I live in rural Washington State (a mile as the crow flies from Dr. Hazzard's infamous Starvation Heights sanitarium). My thriller, THE LAST THING SHE EVER DID, was an Amazon Charts bestseller. LYING NEXT TO ME was a reader favorite, charting at No. 1 in the Kindle store and the bestseller's list at the Washington Post. My true crime book, IF YOU TELL, found a home on Amazon Charts for more than 340 weeks. In fact, it was the bestselling Kindle ebook of 2020 (and the second-bestselling of 2021). THE AMISH WIFE was a finalist for the Mystery Writers of America Edgar Award for best fact crime book in 2025, and OUT OF THE WOODS held the same distinction in 2026. OUT OF THE WOODS was also a nominee for Book of the Year at Crime Con. THE BOY SHE LEFT BEHIND was a finalist for the International Thriller Writers of America Thriller Award for best juvenile novel. I have been a guest on Dateline NBC, NPR, Good Morning America, Early Show, FOX News, CNN, Anderson Cooper, Entertainment Tonight, Inside Edition, Extra, Access Hollywood, 20/20, Snapped, Deadly Women, William Shatner's Aftermath, and A&E's Biography.
