THE DARKEST KISS
When it comes to love, Riley Jenson, a werewolf with vampire blood, can't seem to catch a break. Part of what makes this series so fascinating is the emotional as well as physical battles Riley engages in. Arthur has done a terrific job of taking her heroine from a reluctant fighter to a tough-cookie warrior.
As a guardian for the Directorate, Riley is sent hunting once more when a high-profile politician is murdered. That's only the beginning: An inhuman killer appears to be hunting society strumpets and their lovers.
If that weren't enough, there may be an unusual vampire stalking and killing people connected to his past. For better or worse, that brings ancient vampire and former lover Quinn back into the picture. Their breakup was brutal for both of them; are they willing to risk their hearts once again?
