The women live in fear of the deadly mender’s disease, spread by the sharp needles they use to repair the men’s fishing nets. When Lalani Sarita’s mother pricks her finger and falls ill, she gives twelve-year-old Lalani an impossible task – leave Sanlagita and find the riches of the legendary Mount Isa, which towers on an island to the north. But generations of men and boys have died on the same quest. How can a timid young girl survive the epic tests of the archipelago?
