In Cordelia's London, magic is real and is woven into objects created by the five Maker families: the Hatmakers, the Bootmakers, the Watchmakers, the Cloakmakers, and the Glovemakers. Growing up in her father Prospero's footsteps, eleven-year-old Cordelia Hatmaker has learned the family's ancient skills and secrets so she can one day make her own enchanted hats.

When Prospero and his ship are lost at sea during an important ingredient expedition, her grief-stricken aunt and uncle must turn their attention toward fulfilling a decree to create a Peace Hat for the king. But Cordelia refuses to accept that her father is gone for good and desperately begins making plans to find him. Then, the Peace Hat is stolen--along with the Peace Boots, Watch, Cloak, and Gloves--and Cordelia realizes that there is a more menacing plot against the Makers' Guild, and that Prospero Hatmaker's disappearance may be connected. Cordelia must uncover the truth about who is behind the thefts if she is to save the Makers and find out what really happened to her father.

Full of magic, surprise, and adventure, Tamzin Merchant's sparkling debut introduces a captivating heroine and her extraordinary world.
