My name's Cassia. When my mother died and my father vanished, everything changed.
I planned to graduate high school and leave my dark past behind me, until I met two very different guys... bad boy Thames, and football captain Cairo.
Except there's more to these two men than meets the eye. Without warning, I'm caught up in a dangerous love triangle straight out of a storybook, trapped in a world where angels and demons are fighting for the souls of mankind. I find myself in the middle of a holy war, hunted by a monster that's emerged from the underworld.
My life has been turned upside down, and I don't know if I'll survive long enough to taste forbidden fruit...
