From a young age, Damian Dethridge possessed the unrivaled ability to manipulate and redistribute magic. For centuries, he's been responsible for maintaining the balance among the witch community, and now, his child's extraordinary abilities have lured an old enemy from hiding.

Following her father's footsteps, Sabrina Dethridge is proving to be a formidable force when it comes to witchcraft and has drawn the unwanted attention of an Arcane Devourer. Morcant Thywell, a powerful, chaos-thriving warlock, has set his sights on the young oracle, and by consuming her power, he aims to achieve his ultimate desire-immortality.

Unable to defeat Morcant alone, Damian enlists a rag-tag group of Sentinels to help him neutralize the threat. He'll stop at nothing to protect his daughter because if Morcant wins, Damian's world will be plunged into eternal darkness, and everyone he's ever loved will perish.
