1880. Witches Adelaide Thom and Eleanor St Clair have opened a tea shop in Manhattan specialising in cures, palmistry and potions. When an enchanting woman called Beatrice joins the witches as an apprentice, she soon proves indispensable, but her new life is marred by strange occurrences. She sees things no one else can see. She hears voices no one else can hear. Has she been touched by magic or is she simply losing her mind? Amidst the witches' tug-of-war over how best to nurture her gifts, Beatrice disappears. But was it by choice or by force? In a time when women were corseted, confined and committed for merely speaking their minds, is anyone really safe?
