My rating: 4 of 5 stars 
Genre: Fiction, Mystery, Thriller
A game of psychological hide and seek.
I really enjoyed this book. This mystery/thriller has three plot lines that converge at the end and tie everything together. Two stories occur in the present, and one in 1993. The writing is very engaging, descriptive, and fast paced.
A single mom, Alice, finds a man sitting in the rain on the beach in Cornwall. He looks lost and numb, and she decides to help him find shelter. He is suffering from amnesia and can’t recall his name, background, or why he got there. A young newlywed wife, Lily, realizes that her husband has vanished without a trace. And a story about a brother and sister, Gray and Kristy, idyllic family beach trip takes an unexpected turn when they meet a new friend named Mark. Are these stories related somehow?
The author does a very good job of weaving in the backstory of each character while moving the plot along steadily.
This book, like any good mystery, has characters that you loathe and characters that you get attached to.
I was riveted by the Gray/Kirsty/Mark story more than the other two. Mark was creepy and fascinating. Gray, Kristy, and their family played right into his mind games. Mark’s sociopathic tendencies were horrifying and I was shocked at Kirsty and Gray’s ordeal.
Theirs was the most fascinating and story and as every chapter began I hoped that it would return to that plot line. Well done!
