Dread Knight

Centuries ago, a cabal of powerful mages cast a disastrous spell that corrupted the source of magic, transforming much of the world's population into merciless monsters called Riven. Empires crumbled. Civilization collapsed. Yet an ember of hope remains. Duncan Keene is a Dread Knight, a dark warrior empowered by an unholy pact with a demon lord. He has sacrificed everything to save the world from the Riven—his family, his future, even his very soul. When he finds himself unexpectedly partnered with the last uncorrupted angel in the world, she makes it her mission to redeem him.

Duncan, Kithani, and Vess have survived a gruesome battle, but the war against the Riven horde is far from over. Even bolstered by their new abilities, they are impossibly outnumbered. And as they struggle to unravel the mystery of the dark force threatening the land, they must confront a disturbing truth: that the very magic responsible for destroying the world may be the only chance to save it.
