A sister of the king of Demons—a Nightwalker species gifted with the elemental powers of nature—Magdelegna is an empath and peacekeeper. But ever since she was rescued from a human necromancer's pentagram, Legna has been feeling restless and hot-tempered, no matter how hard she tries to tamp down her warring emotions.

Having existed for more than a millennium, the silver-eyed Gideon is the oldest and most powerful of his kind. A Body Demon, he is a powerful healer, but even he can't cure Legna's long-standing aversion to him. That is, until their latent hostility towards each other explodes into a passionate melding of bodies—and minds.

Legna has no idea what the infusion of Gideon's power will do to a Demon as young as she is, but she's about to find out. A shocking betrayal puts them on the front lines of a battle against the fear, hatred, and prejudice of corrupted humans and their tainted black magic.
