Cardia lives alone in an abandoned mansion outside London because her body carries a poison that corrodes anything her skin touches. Her memories are almost empty, leaving only her father's command to remain hidden and never fall in love. That isolation ends when the Royal Guards break into the mansion to take her away.

She is rescued by the gentleman thief Arsène Lupin, who brings her into a search for the father who may hold the truth behind her condition. Their journey gathers men with remarkable talents and complicated histories, from Victor Frankenstein to Van Helsing. Through conspiracies, inventions, and pursuit, Cardia begins choosing a life for herself instead of accepting the identity of the 'monster' others fear.
