A new magic threatens to destroy Gavin--or change him forever. Gavin has secured the city, preventing the deadly Fates from bringing their terrible sorcery back to Yoran, but Tristan remains at large. Their fight had been a test, and Gavin knows he can't fail the next one. When a strange attack pushes him to reveal the depths of his magic, Gavin knows Tristan has returned to finish what he started. This time, he's working with a power greater than any sorcerer--and something Gavin has never faced. A friend's abduction forces Gavin to take action he never would have considered in order to save them and stop Tristan. He must use all his connections in the city, but even that might not be enough to save them--or stop a plan that's been in play for years. The Chain Breaker will not be enough. He must find a way to become something more than he'd ever trained to be.
