The Obsidian Psalm by Clayton Snyder

SPFBO6

Betrayed by those he trusted. Resurrected by a man he should loathe. A head full of memories he didn’t make. Rook is forced into a bargain that might kill him if he refuses, and if he accepts, could mean the end of existence. Trapped in a shadow war between necromancers, his choices are dwindling to one: Cut a bloody swathe of revenge across humanity’s last remaining city.
