School was finally out. The island was going to be a great place for Tris and Travis to camp, swim, hang out, and just enjoy the summer, away from Mom and Dad. Then one night there were horrible animal sounds in the night, the camp was trashed, food and a sleeping bag disappeared, and Tinker Belle, their dog, was hurt. Could the old box they found have something to do with this? And why did Mandy keep appearing at odd times? Travis worried about his dog. Tris thought more and more about Mandy. And the island became a place to be feared instead of enjoyed.
