On holiday near Rotorua, Joe and Eddie are fascinated by the area's bubbling mud pools and boiling geysers. Local volcanologist Rocky tells them about the Pink and White Terraces that existed on the lake where they're staying, and how they were destroyed in the cataclysmic 1886 eruption of Mount Tarawera. But Joe's fascination turns to unease when strange sightings on the lake and dark rumblings from the Earth hint that the volcano is reawakening. Can he persuade Rocky, who puts his faith only in science, to sound a warning? The past reaches out to touch the present in this spooky adventure story from the author of The Ghosts of Young Nick's Head.
