After twelve years in the Underground City, Ethan Williams will do anything to reach the surface – lie to his mom, steal from a rumored killer. He’ll even drag his sister and best friend into the forbidden Deep Caves, ignoring their concerns about the two experienced cavers who disappeared years ago trying to find a way out.
Maybe he should have listened. Caving sucks. It’s cold and dark, and where’s he supposed to pee? The caves seem more like a death trap than their ticket to freedom, especially when they have to fight off a vicious, possibly rabid bat colony and nearly drown in an icy pool.
It’s all worth it when they see a light. But it’s not the surface, and the cave dwellers they encounter will stop anyone who could expose their secret existence. Those missing cavers? They never made it out. Now Ethan and the girls have to escape all over again. If they fail this time, forget the surface. They can’t even go home. Ever.
