Thirteen-year-old Ppeekk pronounced Peekie finds a very small, very flat, very dead fish. When he comes to life in her hand, he has an amazing story to tell. In the brilliant underwater world called High Voltage, manatees talk, starfish sing, and practical-joking clownfish encourage children to launch their lunchboxes off the bridge. Now, a fiendish, fifty-foot, prehistoric shark has laid siege to High Voltage and dethroned King Frederick the Ninth whom Ppeekk calls Dead Fred. Megalodon, the morphed monster, reigns amphibiously under the old drawbridge with his army of vicious crabs and blood-red remora fish, whose suckers drain victims joy and imagination. Can Ppeekk save High Voltage from the evil Megalodon and return Dead Fred to his rightful throne? Ppeekk and her friends use everything theyve got--exploding coconut bombs, strangler fig lassos, even themselves as human bait--to vanquish the terrifying beast and his rogue army.
