Battle for Cascadia: The Second Book of the Gaia Wars

When thirteen-year-old Warren Wilkes stumbles upon a mysterious relic deep in the Cascade Mountains while fleeing the law (The Gaia Wars) wonder reigns. Brimming with secrets and sentient energy, the relic leads Warren to a fantastic chamber, and to shocking revelations about his identity.

Now wonder has turned to dread.

A forgotten terror-a demon that knows Warren better than he knows himself-has risen again and is gathering power with a singularly evil goal in mind: to capture and enslave the wild spirit of the Earth itself.

Warren must fight or see all that he cherishes destroyed.
