When thirteen-year-old Kate travels to Oregon for a quiet week at Aunt Melanie’s cottage, her plans are dashed by the discovery of a grove of giant redwood trees in nearby Lost Crater. While helping try to protect the redwood forest from loggers, Kate goes back five centuries through a time tunnel and finds herself facing the evil creature Gashra, who is bent on destroying the same forest. In this extraordinary quest from The Adventures of Kate series, a girl discovers that all living things are connected in ways she never expected, and that true friendship can reach across cultures, and even across centuries.
