Murder and Other Mayhem by Sterling Thomas

The shadow killer’s struck again. And again. And again.
Lorelai has seen his kills, and she’s pissed. For him, it’s a game; for her, it’s a curse.
As new revelations about her powers come to light, Lorelai has to focus on controlling them if she ever hopes to bring that Shadowhole down with the help of her men. But if that wasn’t enough, she’s also got to deal with Effie, her best friend, who’s found out about a world that was supposed to stay hidden from her.
Life is never easy when you’re a banshee still trying to find your footing in the supernatural world. It’s almost enough to make a girl look back on being road-kill with fondness.
At least things were simpler then.
