The crimson serpent - book 3

Five elements. One terrifying new world. One final stand. Gabe and his friends thought they had finally discovered a way to destroy the shadow dimension of Arcadia forever.

But they were tricked - and instead of saving San Francisco, they've merged it and Arcadia into one nightmarish reality.

To undo their mistake, they'll have to risk the ultimate sacrifice in a high-stakes battle that will unite all five elements - one last time.
