Laura and her classmates have been looking forward to their senior camping trip for weeks. Three days on an island paradise, away from school and their parents. What more could they ask for?
The camping trip starts out well enough. The island is scenic and just the kind of escape to nature that Laura had hoped for. However, cracks soon begin to appear in her plans. Her boyfriend ditches her to hang out with his friends. She has to share a room with one of the teachers. But those are the least of her worries.
A student disappears, and no one can find him. Soon, Laura and the other students realize that the camping trip is anything but a dream vacation. There’s something else on the island. Something large and frightening. Something that lurks unseen beneath the earth. Something that welcomes the presence of the students because they will satisfy its appetite.
