Beyond the Shadows (Force of Nature #3)

Another day, another problem for Piper Jones and her eclectic mix of allies. And so far, her crew of vampire enforcers, werewolves, and her warlock mentor have come through it all unscathed. But when a rogue assassin starts killing off Knox’s pack, she’s got more to worry about than the faint blue scar on her chest and her failing powers. Now she must race against time to heal her broken magic, if she wants to save the wolves she’s grown to love.
