Shark wars / Altbacker, E. J

With the ocean on the brink of chaos, a young shark Gray and his best friend Barkley, exiled from the safety of their peaceful reef home, will have to battle ferocious shivers, or join them, to survive.

Rising sea temperatures and overfishing have led to a shortage of food, upsetting the order established in the oceans by the Shivers, the prehistoric shark clans that have ruled the underwater world since the dawn of time, and driving Gray, a young reef shark, out into the Open Water to discover his destiny and restore the peace.
