The Darkest Kiss(Riley Jenson Guardian‪)‬

New York Times best-selling author Keri Arthur wields a pen that drips with unrestrained sensuality. In this sexy paranormal romance, Riley Jenson-she of vampire blood and werewolf instinct-is on the hunt for evildoers. As alluring as she is deadly, Riley sets her sights on two imposing serial killers. But when the immortal Quinn joins the hunt, all bets (and possibly Riley's clothes) are most certainly off.
