"A Tom Doherty Associates book."

"After a year filled with harrowing adventures, all Breanna of the Black Wave and her new-found love, Justin Tree, want is a little time to get to know each other better and explore the wonders of the enchanted land of Xanth. But their incipient idyll is soon shattered by a stunning discovery. A climatic catastrophe is causing a massive meltdown that threatens to inundate the ancient forests of Xanth. The only way to avert this dire disaster is to undertake a voyage into the distant mists of the past, to find the moment when this ghastly greenhouse effect began. And the only people who can safely make that journey are those unaffected by Xanth's magic - normal, ordinary humans from our own world."--BOOK JACKET.
