Shadowed Moonlight by K.C. Harper

Loving Kane nearly destroyed Briar once; now that he's Alpha he could be the end of her.

Briar Stone has rebuilt her life since her Were lover, Kane, abandoned her four years ago. She's got a job at a supernatural tavern, a loving magi boyfriend, Mason, and a side-gig reading auras. But none of it matters while her younger brother is a few doses away from killing himself with the psychotropic vampire venom he's hooked on.

When a series of brutal murders targets the local community, the supernatural conclave is sent in to track the serial killer known as the Wraith. But they need help to find answers. Thankfully, Briar can inhabit the dead's final, painful moments and will do so...in return for the money for a cure. But first she needs a way into the conclave, and her ex has just been made Alpha. He agrees to give her access IF she acts as his mate for the duration of the investigation...with all that entails.

Surrounded by the Weres she once hoped to call family, Briar finds herself being dragged back into Kane's world of sex and danger. Balancing her loyalty to her brother, against that of the man she promised to marry, she has to fight her treacherous heart and the growing connection to the lover who ruined her life. But she is not the only one seeking answers. The Wraith has his eyes on her, and he may be closer than she thinks.
