I thought I had the twist. And I did for part, but Riley Sager got me in the end. This book revolves around Ethan who has just returned to his childhood home to live once his parents retire and move. He is back to the home where 30 years ago his best friend, Billy, went missing from the backyard tent both boys were camping in. Just a slash through the tent and a missing boy. No one knows what happened. And Ethan can’t remember a big chunk of it. Then Ethan begins to have strange things happen. A body is found. Is Billy’s ghost haunting Ethan to find the answer? Is he “going crazy” as he suspects? Is someone else playing a cruel joke? Will history repeat? This is absolutely a thriller - and a good one. But it also explores how we all differently deal with grief and loss. How things that seem so perfect often aren’t. I highly recommend!
