Broken bodies and bloody messages are appearing in the darkest corners of New York City. Infected werewolves are roaming the streets attacking innocents.
The Dark Council demands answers. They summon Simon and Tristan to investigate. The evidence points to the work of a powerful mage, unfortunately, there is only one mage in the city powerful enough to cause this kind of infection—Tristan Montague.
Now, Simon and Tristan must locate the source of the magical infection before the Dark Council declares Tristan a dark mage, destroys the werewolves, and shatters the fragile peace in the supernatural community.
