When his best friend Billy mysteriously disappeared in the middle of the night during a backyard campout, it changes Ethan’s life in ways he cannot begin to describe.  Thirty years later, he’s back living in his childhood home and, while having trouble sleeping, he feels a presence that he thinks may be Billy, followed by a clue in his backyard pointing towards Billy.  When Billy’s remains are found soon after, showing he died that night 30 years earlier, Ethan goes through many steps trying to figure out what happened that night, no matter the cost to him or his friends.

Middle of the Night, the latest offering from Riley Sager, continues to tease with the supernatural before explaining away most everything by the end.  I had pegged who was “haunting” Ethan early on, but didn’t key in on who the actual killer was.  With eight books in as many years for Sager, he shows no signs of slowing down.
