Unwanted

"A group of teens are abducted and brought to a secluded, tropical island with no explanation, no supplies and no way off. Left to their own devices and forced to find a way to survive, they soon discover they aren't alone-and their fellow inhabitants are hostile! Things become more complicated when boxes begin to appear on the beach near their camp with weapons and supplies of unknown origin inside. Part Lord of the Flies, part Hunger Games, this is a story of survival where you can't trust anyone."
