Crown Park

Jack Stewart hates his new life in Taupo. Everyone at school picks on him; his only friend is a stray cat called Chainsaw; and his parents are always away working.

Then he meets Fluoro, who lives in an old explosion crater in Crown Park where steam and poisonous gases hiss and ooze from the ground. Jack finds that Fluoro has chosen this place not just for the heat coming from deep inside the earth, but because it provides a link to the last eruption of Lake Taupo, two thousand years before.

With Fluoro's help, Jack learns how to take his mind back to when moa and other ancient animals faced the world's greatest eruption. Along with a group of creatures called the Luce Crew, they embark on a rescue mission that threatens not only these animals of the past, but humans in the present.
