Darwin, 1942, and as Japanese bombs rain down, orphan Molly Hook is looking to the skies and running for her life. Inside a duffel bag she carries a stone heart, alongside a map to lead her to Longcoat Bob, the deep-country sorcerer who she believes put a curse on her family. By her side are the most unlikely travelling companions: Greta, a razor-tongued actress, and Yukio, a fallen Japanese fighter pilot.
