Uncharted

"I'm beginning to think the island wants to keep us here." It was supposed to be an adventure. A little time off to honor the memory of a friend and complete a service project in the tropics. Do good deeds while getting a tan. But when a storm rocks their plans, five long-time friends from college find themselves hurled onto a desolate island, and relief fades to fear. Here nature rules with a vengenance. The lone shelter from raw conditions is a sinister cave. Are they victims of a bizarre psychological experiment? Or could this godforsaken place have the power to maroon them forever?
