"Since the dawn of time, prehistoric shark clans called shivers have ruled over the earth's oceans. For eons, the Big Blue has prospered under Shiver Law, and the delicate balance of sea life kept sacred. Until now. When a young shark named Gray is exiled from the safety of his peaceful reef home, he and his best friend Barkley find themselves forced to venture out into open water. In the dangerous open ocean, the two friends learn that not all sharks are interested in upholding Shiver Law, and some sharks are even trying to destroy it. With the ocean on the brink of chaos, Gray must work with his friends to take down the corrupt shivers and bring peace back to the ocean. But first, he'll have to unlock the secrets of his destiny and discover the truth about who--and what--he really is."--Publisher's website.
