Five Survive by Holly Jackson

Eighteen year old Red and her friends are on a road trip in an RV, heading to the beach for Spring Break. It’s a long drive but spirits are high. Until the RV breaks down in the middle of nowhere. There’s no mobile phone reception and nobody around to help. And as the wheels are shot out, one by one, the friends realize that this is no accident. There’s a sniper out there in the dark watching them and he knows exactly who they are. One of the group has a secret that the sniper is willing to kill for.
