As dawn breaks on All Souls Day, the lingering mists part to unveil an unending vista of serried gravestones. Between them looms a theatre like a haunted house and the sleek iron carapace of a steam train – the Pearl. On board are the cast, orchestra and crew of a travelling ballet company, performing The Apple and the Pearl.

As he stumbles toward the restaurant car the lighting director, Zach, asks the new recruit, Lara, “Have you ever worked in ballet before?

"Have you had any contact with the supernatural?”

Everyone from the principal ballerina to the first violinist, from the wardrobe mistress to the newest members of the corps de ballet, have committed their lives to the perfection of the show. But every night they must also confront the malevolent glamour of their audience of Fae creatures only too eager to snatch them away into the Otherworld.
