In New York City, 1897, life has never been more thrilling—or dangerous. Sixteen-year-old Finley Jayne and her "straynge band of mysfits" have journeyed from London to America to rescue their friend Jasper. Jasper lies in the clutches of a devious former friend demanding a trade–the dangerous device Jasper stole from him for the life of the girl Jasper loves. One false move from Jasper, and the strange clockwork collar around Mei's neck tightens. And tightens. To help those she's come to care for so deeply, Finley Jayne must infiltrate a criminal gang, and more than ever rely on powerful English duke Griffin King to balance her dark magic with her good side. At war with himself over his secret attraction to Finley, Griffin will risk his life and reputation to save her. Only problem is, Finley might like the dark side a little too much...
