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.","forthcoming":false,"isbn13":"9781542005234","publication_date":"20191201","publisher":"Amazon Publishing","slug":"if-you-tell","subtitle":"A True Story of Murder, Family Secrets, and the Unbreakable Bond of Sisterhood","title":"If You Tell"},"discovery":{"categories":{"all":[{"bisac_code":"TRU002010","confidence_band":"medium","label":"Serial Killers","score":0.8002,"source":"bisac_hint_model"},{"bisac_code":"TRU002020","confidence_band":"medium","label":"Mass Murder Cases","score":0.7878,"source":"bisac_hint_model"},{"bisac_code":"FIC031080","confidence_band":"medium","label":"Psychological Thrillers","score":0.7831,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"TRU002010","confidence_band":"medium","label":"Serial Killers","score":0.8002,"source":"bisac_hint_model"},{"bisac_code":"TRU002020","confidence_band":"medium","label":"Mass Murder Cases","score":0.7878,"source":"bisac_hint_model"},{"bisac_code":"FIC031080","confidence_band":"medium","label":"Psychological Thrillers","score":0.7831,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"TRU002000","confidence_band":"high","label":"Murder & Homicide","score":1,"source":"onix_publisher_code"},{"bisac_code":"TRU002010","confidence_band":"high","label":"Serial Killers","score":1,"source":"onix_publisher_code"},{"bisac_code":"TRU006000","confidence_band":"high","label":"Abductions & Missing Persons","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Serial Killers","score":0.8002,"slug":"serial-killers"},{"label":"Mass Murder Cases","score":0.7878,"slug":"mass-murder-cases"},{"label":"Psychological Thrillers","score":0.7831,"slug":"psychological-thrillers"}],"reader_fit":["Good for readers who enjoy Serial Killers","Good for readers interested in book club","Good for fans of True Crime"],"related_lists":[{"intro":"","slug":"shelf-tru002020-mass-murder","title":"Mass Murder Books","url":"https://bookfrontier.com/lists/shelf-tru002020-mass-murder"},{"intro":"","slug":"shelf-tru002010-serial-killers","title":"Serial Killers Books","url":"https://bookfrontier.com/lists/shelf-tru002010-serial-killers"}],"series":null,"similar_books":[{"authors":["Gregg Olsen","Karen Peakes","Hachette UK - Thread","& 0 more"],"book_id":"9781538724859","cover_image_url":"https://img.bookfrontier.com/9781538724859.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":25.0456,"title":"American Mother","url":"https://bookfrontier.com/books/9781538724859"},{"authors":["Gregg Olsen"],"book_id":"9781662514180","cover_image_url":"https://img.bookfrontier.com/9781662514180.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":22.9952,"title":"The Amish Wife","url":"https://bookfrontier.com/books/9781662514180"},{"authors":["Gregg Olsen","Rebecca Morris"],"book_id":"9781250118707","cover_image_url":"https://img.bookfrontier.com/9781250118707.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":22.1111,"title":"A Killing in Amish Country","url":"https://bookfrontier.com/books/9781250118707"},{"authors":["Michelle McNamara","Gabra Zackman","Gillian Flynn","Patton Oswalt"],"book_id":"9780062319791","cover_image_url":"https://img.bookfrontier.com/9780062319791.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":20.4257,"title":"I'll Be Gone in the Dark","url":"https://bookfrontier.com/books/9780062319791"},{"authors":["Jillian Lauren","Michael Connelly"],"book_id":"9781728267753","cover_image_url":"https://img.bookfrontier.com/9781728267753.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":20.3814,"title":"Behold the Monster","url":"https://bookfrontier.com/books/9781728267753"},{"authors":["Ann Rule","Lorelei King","Simon & Schuster Audio"],"book_id":"9781501139147","cover_image_url":"https://img.bookfrontier.com/9781501139147.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":20.3535,"title":"The Stranger Beside Me","url":"https://bookfrontier.com/books/9781501139147"},{"authors":["Kathryn Casey"],"book_id":"9780061230875","cover_image_url":"https://img.bookfrontier.com/9780061230875.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":18.6659,"title":"A Descent Into Hell","url":"https://bookfrontier.com/books/9780061230875"},{"authors":["John Coston","A.
