The Erased

It's never too late. Holly and her friends are placed in charge of a snow-covered camp in a mysterious location. When they locate the camp, they're surprised to find it empty, but it isn't long before people start to arrive. At first, everything seems to be going smoothly, but when something outside their protective fence threatens the lives of everyone inside the camp, they quickly realize no one is going to help them. They are entirely alone. The four of them must do whatever it takes to keep themselves alive before the entire camp is wiped out of existence. Find out how it all ends in The Erased, the final book in The Island series!
