Jack Stewart hates his new life in Taupo until he meets Fluoro, Taupo's most visible street person. Fluoro lives in a old explosion crater in Crown Park, which provides a link to the last eruption of Lake Taupo, two thousand years before. With Fluoro's help, Jack learns to take his mind back to that time and, with a group of creatures called the Luce Crew, embarks on a mission to rescue the animals of the past from the eruption. Suggested level: primary, intermediate.
