Nina is a Lipan girl in our world. She's always felt there was something more out there: she still believes in the old stories. Oli is a cottonmouth kid, from the land of spirits and monsters. Like all cottonmouths, he's been cast from home, but found a new one on the banks of the bottomless lake. Nina and Oli have no idea the other exists-- until a catastrophic event on Earth. When a strange sickness befalls Oli's best friend, it will drive their worlds together in ways they haven't been in centuries. And there are some who will kill to keep them apart. -- adapted from back cover
