Damselfly

In the wake of crash-landing on a deserted tropical island, a group of private-school teens must rely on their wits and one another to survive.Their survival is in their own hands … Samantha Mishra opens her eyes and discovers she's alone and injured in the thick of a jungle. She has no idea where she is, or what happened to the plane taking her and the rest of the Drake Rosemont fencing team across the Pacific for a tournament. Once Sam connects with her best friend, Mel, and they find the others, they set up shelter and hope for rescue. But as the days pass, the teens realize they're on their own, stranded on an island with a mysterious presence that taunts and threatens them. Soon Sam and her companions discover they need to survive more than the jungle . . . they need to survive each other.
This taut novel, with a setting evocative of Lord of the Flies, is by turns cinematic and intimate, and always thought-provoking.
