An epidemic is overloading Baltimore hospitals, and this time the vampires are finding themselves susceptible. Those infected are unable to control their hunger, crazed and insatiable no matter how much blood they consume. The timing couldn’t be worse, with a rival Balaj in town for a feast – a rival that would be happy to take advantage of the situation and wrestle control of the Baltimore territory from Dario and his family. As the Baltimore’s Templar, Aria must find out who – or what – is responsible and stop them, before the entire city is at death’s door, all while prepping for the Halloween ritual to rid herself of a demon’s mark on both her skin and her soul.
