"Lost Crater is like no other place on the planet...stranger than you can imagine." A log collapsed in the fireplace, sending up a shower of sparks. "The Ancient One lives there." When Kate travels to Blade, Oregon, for a quiet week at Aunt Melanie's cottage, her plans are dashed by the discovery of grove of giant redwood trees in nearby Lost Crater. For thousands of years, no humans have entered the fog-filled crater--except possibly the Halami people who lived in the region centuries ago before vanishing without a trace. Long a source of deep mystery, the crater is now a source of conflict, pitting those who see it as the dying mill town's last hope against those who see it as a rare sanctuary that should be protected. Caught up in this struggle, Kate follows an old Halami trail into the crater, and suddenly is thrown back in time five hundred years. Accompanied by the trickster Kandeldandel, the loyal Laioni, and the young logger Jody, she meets strange and enigmatic creatures, none more frightening than the volcanic Gashra, bent on destroying everything he cannot control. To defeat him, Kate must find the answer to an ancient riddle--and the courage to make the most difficult choice of her life. In this extraordinary quest, combining high adventure and heroic drama, 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.
