A riveting psychological suspense debut that weaves a mystery about a childhood game gone dangerously awry, and will keep readers guessing right up to the shocking ending.

In 1986, Eddie and his friends are on the verge of adolescence, spending their days biking in search of adventure. The chalk men are their secret code, stick figures they draw for one another as hidden messages. But one morning the friends find a chalk man leading them to the woods. They follow the message, only to find the dead body of a teenage girl.

In 2016, Eddie is nursing a drinking problem and trying to forget his past, until one day he gets a letter containing a chalk man—the same one he and his friends saw when they found the body. Soon he learns that all his old friends received the same note. When one of them is killed, Eddie realizes that saving himself means figuring out what happened all those years ago. But digging into the past proves more dangerous than he could have known. Because in this town, everyone has secrets, no one is innocent, and some will do anything to bury the truth.
