From the author of The Assassin Game and Have You Seen My Sister? comes another gripping thriller that follows seven teens stranded together on a trip in the mountains, cut off from civilization, and hunted by an unknown killer who wants them dead. 

Maggie Atkins will never forget what happened in that cave ten years ago when she and six other elementary school kids were kidnapped by their bus driver and kept captive. She will never forget that her friends left her alone to escape, or the image of her kidnapper falling to his death, but she has done her best to put the ordeal behind her and move on.  

Her past catches up with her when she's forced to go on a school trip to the mountains with the very same people who abandoned her, and only a stone's throw away from the scene of her kidnapping. She's determined to suck it up and get through it though since it's only one night of her life. But then a brutal storm changes everything and separates her group from their chaperone. With no phones and a limited food supply, the group strategizes how they can survive the elements and make it back to safety.  

Then they realize there is someone else on the mountain. Someone who knows what really happened all those years ago. Someone who wants them dead and is willing to take them out one by one. Maggie thought she'd already survived the worst thing she would ever go through—she was wrong.
