Summer camp at Rim of the World has barely begun when four misfit teenagers -- Alex, ZhenZhen, Dariush, and Gabriel -- find they've got bigger problems to face than learning how to canoe and climb ropes when aliens suddenly invade the planet. Alone in a campground once teeming with people, the kids are unexpectedly entrusted with a key that carries the secret to stopping the invasion. Without any adults or electronics to help guide the way, it's clear what they must do: band together, conquer their fears, and save the world.
