A story of ancestral power, friendship, and shadows... When thirteen year old Anne's imaginary friend comes back, she assumes it's because she's been alone too much. But she doesn't expect it to put her own life, and those of the people around her, into so much danger. Then her cousin Milly reveals that they share a family secret, and Anne realises she has to brave her terrifying dreams and decode her grandma's instructions so that she can face the shadow that's stalking her. And in the process, she might just find that she's not as alone as she thought.
