Cathy's book - Sean Stewart

When 17-year-old Cathy wakes up one morning to discover a needlepoint near her elbow, her mother is typically suspicious and worried. But Cathy has other ideas and quickly puts them into action. In pursuit of her missing boyfriend (who she feels must be linked to the strange mark on her arm) she starts piecing some startling facts together which lead her into the dangerous underworld of San Francisco's China Town.

Throughout her findings, Cathy keeps a secret journal and gathers many items of evidence as well as telephone numbers and websites - leaving it all for her friend Emma to find should Cathy go too far and not come back. All this evidence can be found, integrated into the book and also available to download online.

Readers who fully explore this compelling and unique novel, will enter an alternate reality as they reach deeper into the thrilling mystery of Cathy's world.
