Madness is spreading like a virus. Ninety years ago, Gabriella di Luca failed to protect the family of her dead lover. Now the devil that murdered the eldest Van Helsing son has resurfaced, and she’s determined to stop him before he can lay a bloody hand on the remaining three brothers. However, Gabby suspects the devil is testing a drug that induces demonic possession, and the only way to stop the devil’s plot is to fall victim to the madness herself. If she wants to save the brothers and their city, she’ll have to risk most precious possession: her mind. If you enjoy Kim Harrison and Laurell K.
