Ava has moved to yet another new town, in the middle of the first semester senior year. Being the new girl sucks, but Mountainridge holds secrets and monsters that outweigh her school issues. Her life will never be the same once school bully Kaen tears into her life like a wildfire.

Kaen's life won't be the same either, and his life isn't the only one that is forever changed by Ava coming to town. The secrets and balance he's spent years holding tightly are in danger, and he may not be strong enough to keep it together. He knows what he's hiding in his skinchanger’s heart, but he never would have guessed the secrets Ava didn't even know she had.

A witch's plot finally erupts, throwing the tiny mountain town - and the world - into chaos. Will Kaen and Ava survive her poisonous spells, or will the world fall into darkness? The future of humanity rests in the hands of those who aren't even human, to keep the light shining in the world.
