Deep Midnight by Heather Graham

The hour when dreams turn into nightmares...
 Hosted by the Contessa Della Trieste, an opulent Carnevale ball in Venice takes a terrifying turn for American Book critic Jordan Riley. As festivity turns into frenzy, Jordan is rescued by a powerful man disguised as a wolf. But was the mayhem she witnessed-the blood-the fangs, the screams-truly just entertainment or something far more sinister?
