'Something once lost can never be returned...' Ciel Phantomhive had no idea that by stepping into the mansion she inherited from a grandfather she never knew, that life as she previously knew it would end. As her foot crossed the threshold of the master's chambers her fate was sealed and a series of unchangeable events would forever leave the teenager's life tied to a devil. Sebastian Michaelis had been on a search for the better half of a century for the one soul that got away. He stumbles upon what he seeks at the most unexpected of places; the last Phantomhive heir who has an uncanny resemblance to his pervious young master. The beginning of an exception is born.
