Dark Flames (Blood Bound Book 6) by RK Melton

Just as the vampire war escalates into a full-blown demon war, Zachary finds himself responsible for a beautiful necromancer who is connected to a dark moment in his past. He had watched her mother step across the thin line and straight into the arms of a demon. It was his job to make sure Tiara didn’t choose the same lustful path… unless it was with him. Now, with the demons closing in, the last thing he expected was for Tiara to be kin to them. As tempers soar and secrets are kept, jealously becomes a dangerous game. Someone should have warned her that when you play with fire you are bound to be burned. PUBLISHER: TEKTIME
