Marcus King thought he had it all figured out. As a Shadowguard, he protected New York City from supernatural threats with his quick wit and even quicker feet. But when a mysterious vigilante named Julian White bursts onto the scene, Marcus's world is turned upside down.

Julian is everything Marcus isn't - brooding, powerful, and infuriatingly attractive. As a series of magical attacks rocks the city, Marcus and Julian find themselves reluctantly working together to uncover a sinister plot that threatens everything they hold dear.

But as the danger mounts and their connection deepens, Marcus and Julian must confront their own demons and the shocking truth of their intertwined destinies. With time running out and a powerful enemy closing in, they'll have to decide if they can trust each other - and their growing feelings - to save New York and possibly the world.
