One night out of all the centuries changed their lives forever... Called to the scene of a double murder, police officer Colton Killion finds that the vicious attack by vampires has not only decimated his family, but the trauma from it transforms him into a rare ghost wolf. Now he's on a life-and-death mission to restore justice. The last thing he needs is a distraction—especially when it comes in the lithe, female form of Lycan Rosalind Kirk. But Rosalind needs his help as much as he can't ignore his insatiable attraction to her. For that very attack also infused Rosalind with the spirit of a Banshee... and now Colton is the only being who can protect her from Others. When evil strikes again, Rosalind and Colton must risk everything by crossing a forbidden line... consequences be damned.
