"The oceans of the Jurassic world were filled with nightmarish creatures. Plesiosaurs, long-necked reptiles measuring up to twenty-five feet long, ate fishand each other. The 40-foot-long Kronosaurus and the 45-foot-long Liopleurodon were ferocious predators with razor-sharp teeth. They ate anything they could catch. Alongside these megapredators swam Hybodus, whose descendants include the great white sharks of today. Hybodus was not the largest hunter in the Jurassic seas, but it was fearless. Hybodus would attack anything. This is the story of a female Hybodus and her struggle to survive. She must find a way to keep from being eaten, even as she hunts for food herself. She must fight off a Liopleurodon that attempts to take over her hunting grounds. And she must find a way to keep herself, and her unborn baby, safe in a place where even the deadliest of hunters can become meals for other predators. Discover how she responds to the challengesand survives."
