Jael Thompson has a huge secret. Her mother, who died when she was a baby, was a demon. Her father, an ex-priest, moves them around constantly, to protect Jael from forces that would try to either kill her or use her for evil purposes.
When Jael turns 16, her dad gives her a necklace he promised he would. With that gift, everything changes. Her dad doesn't want to tell her anything, but before long, he has to. Her demon half is making itself known. She can't control her emotions and the demon who killed her mother is now after her.
The story starts a little slow, but that's only the first chapter. Flashbacks and memories surface through the book. Lots of dialogue, action, and a little romance round out this supernatural story. There's some mythology as well.
