A long but well-peopled fantasy with a strong environmental message. When Kate, 13, tries to help stop a group of unemployed Oregon loggers from cutting a unique stand of redwoods, she's cast back five centuries and propelled into the struggle against Gashra, a megalomaniac volcano creature with a very real scorched earth policy.'' The strongest feature of this novel is not the wandering, predictable plot but the colorful cast, especially the nonhumans- -boulder-like Stonehags, many-eyed underwater Guardians, lizard-folk, owl-folk, and (best of all) the monstrous Gashra, a delicious combination of tyrannosaur, octopus, and two-year-old- -who add a strong dash of humor as well as occasional prophecies and rescues. In the end, Kate recovers a stolen power crystal, sends Gashra back into the earth for a few more centuries (take heed), and returns to her own time to witness one last desperate logger felling the oldest redwood just before a protective injunction takes effect.
