Can a human heart overcome a demon soul? When soul-eating demons overrun his world, Kaelis, a young seraph warrior, uses the Queen's ring to open a portal in space and flee with the infant heir to the throne, landing on earth. Unbeknownst to him, the demon leader, Nsark, follows through the portal, determined to devour the soul of every last seraph, especially the Queen's heir. After Kaelis hides the baby, Nsark creates the ultimate weapon by fathering a half-human, half-demon: a soul-stealer's child. Sixteen years later, James struggles to fit in with his peers. In a last-ditch effort, he joins the school play, where he meets Lucy. Something deep draws them together, and their friendship reveals their hidden pasts: one is an angel, one is half-demon. Lucy and James find themselves pulled into an age-old war between their peoples. Hunted by relentless enemies, and grappling with deep-seated instincts and strange new powers, they must fight for their lives, their souls, and each other. Can they overcome who they were born to be, or will one of them have to make the ultimate sacrifice for the other to survive?
