About this book

Book Summary

Two families at a secluded lake resort are at the center of a chilling crime in this twisty thriller from the bestselling author of Local Woman Missing.

A scream shatters the silence… Courtney Gray's peaceful vacation turns into a nightmare when she discovers her brother and sister-in-law dead in their lakeside cottage. Her niece Reese is missing. Her nephew Wyatt is asleep upstairs—unharmed.

A town full of secrets… As police swarm the quiet resort, dark truths about Courtney's family—and the town itself—begin to surface. Is Reese a victim… or the killer?

A truth no one saw coming… With everyone hiding something, Courtney races to uncover the terrible mystery. But the closer she gets, the harder it is to know who—or what—to trust.

Couldn’t stop reading it
I stayed up way to late but I simply had to finish this book! What a psychological thriller! I just didn't see that ending coming either. Sister Courtney and her family (husband Elliot, and daughter, Cass) along with her brother Nolan and his family (wife, Emily, daughters Reese and Mae, and son, Wyatt) are vacationing at a lake in Wisconsin when a horrific event occurs that shatters both families and involves a child is missing, much like the missing girl, Kylie, who disappeared five years before.

Courtney is overwrought that her niece is missing and the police seem to be doing nothing about it. She investigates but while discovering some clues, nothing results in finding her niece until a clue leads them to her. But there's more, though you'll have to read the book to find out what it is. The atmosphere surrounding this book is creepy and chilling. The woods surrounding the resort - which to my way of thinking was old and rundown - are dark and filled with ominous danger. The manager of the resort, Mrs. Dahl, and her handy man, Daniel Clarke, seem sinister. The whole place is forbidding. Even the characters are a bit off and add to the tension and creepiness. Reese, the missing niece, is such an angry bitter child due in part to bullying at school; her parents' marriage is on the rocks, and her brother, Wyatt, is awful. Courtney is falling apart seeing murderers everywhere, even her husband, and what her daughter and niece, Mae did, is appalling. All of this intensifies the psychological aspects of this thriller.

This is my very first Mary Kubica book but it won’t be my last.
