In this reimagined fantastical tale about the lives of nineteenth century writer Mary Shelley and mechanical engineer Ada Lovelace, the pair become fast friends after meeting at a party. While Mary wonders if she'll ever get a great idea for a novel, Ada studiously works to bring her robot Pan (Practical Automaton Number One) to life. In a strange turn of events, the girls meet their fairy godmother Miss Stamp, who tells them they are part-fae and have magical abilities to make real what they imagine. Mary tests out the theory and brings Pan to life. Soon, a host of determined and ruthless scientists are after their technology and they must fight to keep their abilities a secret and their robot for themselves.
