A fantastical adventure through the world of the Cloud Hunters. In a world where islands float above the sun and Cloud Hunters sail the skies for water, orphans Gemma and Martin live with their 120-year-old great, great, grand aunt Peggy and the sky-cat Botcher on a remote rock miles from civilisation. When Peggy decides they should visit City Island to register at school, the group embarks on a trip that will take them through uncharted territories, navigating a very dangerous sky. Encountering cloud pirates, sky rats and an axe murdering motel owner, Gemma and Martin must learn to fend for themselves, and fight for what's right in a perilous world. In this sequel to Alex Shearer's CLOUD HUNTERS, SKY RUN returns to a fantasy world filled with adventure, escapism and a sense of magic at every turn.
