Fairyland's future lies in doubt... The island of Janda Baik, in the Malay archipelago, has long been home to witches. And Muna and her sister Satki wake on its shores under a curse - which has stolen away their memories. Satki plots to banish it in London, as Britain's Sorceress Royal dares to train female magicians. But the pair journey there via the Fairy Queen's realm, where Satki disappears. Distraught, Muna takes her sister's place at the school, despite her troublesome lack of magic. Then the Sorceress receives an ambassador from the Fairy Court, which has incarcerated her friends - for supposedly stealing a powerful talisman. Their Queen is at her most dangerous, fearing for her throne. For the missing trinket contained the magic of her usurped sister, Fairyland's rightful heir. Mina must somehow find Satki, break their curse and stay out of trouble. But if the true queen does finally return, trouble may find her first...
