At the Wyldcliffe Abbey School for Young Ladies, Sarah Fitzalan is the dependable, faithful friend to Evie and Helen, her sisters in the Mystic Way. But this term Sarah encounters new challenges: Evie seems to have turned her back on the Mystic Way after the sisterhood laid Sebastian's soul to rest, and Helen is distracted by her still-unresolved feelings about her mother, Mrs. Hartle. Sarah is lonely and worried. Unlike Evie, she wants to find out more about her own Mystic powers and her strong connection to the earth, and she struggles to keep the sisterhood together as the threat of attack looms from the ever-present dark coven at Wyldcliffe. And so it is up to Sarah to face the eternal darkness and fight. Must she sacrifice herself for the sake of her friends and sisters? When she feels her loneliest, will her sisters join her, or will help come from unexpected sources, like her Romany ancestors, and a love she'd only just dared to hope for?
