Imperceptible to most, a supernatural dimension--one filled with evil spirits, and worse--operates alongside our own. A barrier protects us from them, but deep in a forest cave the ancient Hermit labors to destroy that barrier. Then there will be nothing to stop the tide of evil from overtaking our world.

After a terrible accident, fourteen year old Red Snyder discovers he has the ability to cross into the spiritual world and finds himself face to face with the evil menace. With his father in danger and the enemy closing in, Red resolves to fight, but he can't do it alone. An unlikely coalition forms around Red--Tom, an old man who knows about the spirit world; Michael, Red s loyal lifelong best friend; Wendy, the child genius; Chase, a martial arts master turned vigilante; and Esm , an escaped circus performer--and together they stand as the last best hope of all mankind.
