From publisher blurb:
For thousands of years the medusae have slumbered beneath the Statue Hills, waking only once every century or so to check on their minions and put their long-term plans into action. The return of the ophidae has given them new hope, for now it is possible to sire a new generation. Soon their eggs will hatch. Soon the hatchlings will grow to adulthood. Soon the medusae will emerge from the subterranean homes to conquer the surrounding desert.
