Shinoni and Keena are about the same age, thirteen, but are as different as two girls can be. One is the member of a human tribe, while the other stems from the disliked Neanderthals. They have nothing in common outside of the world they live in, and that one is harsh and unforgiving. But when an evil hunter steals both from their families, they soon form an, otherwise, impossible bond. Not only do they need to escape and return to their families, but, more importantly, they'll need to survive.
