A Madness of Angels — Kate Griffin

Two years after his untimely death, Matthew Swift finds himself breathing once again, lying in bed in his London home.

Except that it's no longer his bed, or his home. And the last time this sorcerer was seen alive, an unknown assailant had gouged a hole so deep in his chest that his death was irrefutable...despite his body never being found.

He doesn't have long to mull over his resurrection, though, or the changes that have been wrought upon him. His only concern now is vengeance. Vengeance upon his monstrous killer and vengeance upon the one who brought him back.
