Superpowers from hot springs? Who knew? Anira thinks her family's trip to Rotorua, New Zealand, will be a week of grudging participation as she fights off a latent phobia of volcanoes. But this place has ancient secrets she could never have imagined. For its natural geology and untamed thermal forces hold a hidden power—one that transforms those gifted by the spirits of the land. Now Anira finds herself possessing abilities she has never known. There are others like her—young and old, both good and evil...And the legendary guardians have a job for them to do. Together they are caught up in a race against the developer intent on destroying the natural springs that are the home of the ancients and the source of their powers.
