Josh, Grace, and Logan weren't a traditional family; Josh and Grace never married, and Josh never formally adopted Grace's son, Logan, but they were as committed to each other as any other family in their idyllic Maine neighborhood. But when Grace passes away unexpectedly, their laissez-faire attitude towards legal partnership catches up with Josh. As he sorts through paperwork to establish paternity of Logan, he uncovers a secret he's wholly unprepared to confront. Josh starts untangling the complicated web of Logan's early life, and realizes that Grace had a multitude of reasons to keep their family's records incomplete. A thrilling contribution to the domestic-suspense genre popularized by Gone Girl (2012) and The Girl on the Train (2015), McKinnon's (The Neighbors, 2018) latest blends a sinister origin story with a man's singular quest to uncover the truth, no matter how troubling. McKinnon explores the reasons for revising one's own history, and why some secrets are better left unanswered. Fans of Heather Gudenkauf and Tana French will sink their teeth into this fast-paced, twisty thriller.--Stephanie Turza Copyright 2019 Booklist
