The Dreaded by D.E. Chapman

Theo may have not wanted this omega, but that doesn’t mean he’s going to let her go. She’s his, and that means any alpha who tastes her estrous or her blood is a dead man walking. Everyone in Darvus knows the du Sangs don’t share.
But it seems like someone didn’t get the memo.
Anna didn’t flee the penthouse like the brothers first thought; she was abducted by their enemy, and now it’s time to narrow down precisely which pack is responsible. A little digging uncovers a traitor in their midst, which means it’s time to clean house. No one will survive the du Sangs’ wrath with their sanity still intact.
Not even their little mate.
