Turncloak

Three rival mages race for power, vengeance, and the fate of Atherin in the epic second installment of the Silvercloak Saga, from the #1 New York Times bestselling author of Our Infinite Fates. Revenge drove Saffron Killoran to go undercover in the Bloodmoon gang. But now, with any chance of retribution gone, she sees only one path forward: harnessing a long-dormant power to fix her ruinous mistakes.
Meanwhile, the new kingpin of the Bloodmoons has discovered Saffron's true identity as a Silvercloak-and her ultimate goal of bringing his empire down. As old wounds resurface and fresh enemies close in, he finds himself torn between the cause to which he has devoted his life and the fate of the traitorous mage he loves. Hot on their heels is an ambitious rookie detective sent to stake out the Bloodmoons' growing rivals.
She will stop at nothing to destroy both gangs-and anything or anyone who dares to stand in her way. Caught in a cat-and-mouse game of trust and betrayal spanning continents, Saffron must choose where her loyalties lie-and determine if her quest to unmake time itself is worth becoming a villain to the whole world.
