They're called the Nightwalkers - proud, ancient beings who live beyond the shadows, existing just beyond the human world. But there are also dangerous humans who hunt them. And for a Demon named Gideon, the battle against these evil forces will soon become all too personal . . .

For a thousand years, Gideon's wisdom has always been respected without question, but he knows that even he is vulnerable to the powerful, primitive desires that befall his kind during Hallowed moons - as nine years ago he found himself claiming Magdelegna, the Demon King's sister, in a wild embrace. Horrified by his lack of control, he left her wanting and furious - and then exiled himself. Now with the necromancers threatening his people - and Magdelegna nearly their victim - Gideon must face another truth. He and Magdelegna are destined to be together. But first he needs to regain her trust, which might be the biggest challenge of all.
