Reapers (The Unnaturals #4)
A near-legendary figure with a haunted past, Abdiel has been granted a single chance at redemption. His mission: to protect the Witnesses at all costs, even if it means his life. Again.
But the mission is rife with problems. The Witnesses don’t trust him. The Mother of All Dark Things and her demons are not only still after them, but they’re gunning for the goal of opening the gates of Hell itself. And his charges have managed to unwittingly unlock the beginnings of their powers without any idea how to use them. It’s up to Abdiel to not only teach them now to wield their powers, but to also help stop Ahm before it’s too late.
Reapers is the fourth book in The Unnaturals Series.
