All her life, a faint memory of her parents and fire has glowed at the back of Rachel Quinn's mind. With her parents long dead, there is no one to clarify what it means.

When a gorgeous winged man rescues her from a pack of werewolves, something flares to life inside Rachel. Suddenly she can see the paranormal world around her, a world unseen by mortals. And far more complicated.

When Phoenix's massive orange-and-red wings erupt from his back, he knows his Challenge-an age-old battle against his Demonos counterpart-is upon him. Heeding Rachel's cry for help adds a layer of complexity never seen in any previous Challenge.

Rachel, they discover, isn't entirely human. Like Phoenix, she commands fire. Fire calls to fire, and soon they are succumbing to a fierce attraction. As the Challenge bears down on them, though, Phoenix must discover what the Demonos has in store for mankind. If he doesn't succeed, the entire world will be swallowed up in darkness-and Rachel along with it.
