Deadly Vows - The Lizzie Grace Series, #6

Evil comes in all forms . and sometimes it wears a human mask. When the body of a newlywed is discovered on the reservation, Lizzie Grace throws herself into the investigation, needing a distraction from what she fears is coming not only for her but also Belle-her best friend and witch familiar. But as the body count grows and a desperate race begins to track down a supernatural entity capable of powerful magic, it becomes evident another deadly game has begun-one they may not win.
Because the past-and the man-they ran from thirteen years ago has finally caught up with them. And he's out for revenge.
