The power to alter reality makes Tadgh the most powerful man on the planet. That's why the demons want him.

Three hundred years ago, a group of heroes imprisoned a dark god and his lieutenants in a hell dimension known as the Void. Since then, the people of Maghe Sihre have lived in relative peace. Now, a secret war brews at the edge of civilization.

Tadgh Dooley, a young man from Earth, is burdened with a dangerous and impossible power. He has the ability to warp the fabric of reality, to make his wishes come true. One wish binds him to the spirit of a demon cat. Now he is a shapeshifter, a werecat. The armies of evil see him as a weapon. They will not rest until they control him.

A mysterious force transports Tadgh to Maghe Sihre and, in doing so, ruptures the Void. Worse, each time he uses his ability, the Void cracks open a little further. Prisoners start to escape. If Tadgh can't control his power, he risks shattering the Void completely, unleashing the dark god on an unprepared world.
