Into the Abyss

Gray, Barkley, and the alliance of Rogue, Coral, and AuzyAuzy Shivers have defeated the maniacal emperor Finnivus and his vicious Indi Shiver armada. But Finnivus is still plotting. This is the ruler who feasts on the heads of every shark he conquers, after all.
When Finnivus's gangs of soldier fish strike, Gray and his friends endure a loss bigger than any before. And this time there's no one left to tell Gray what to do. He's got to lead the rebels into battle for the ultimate fight of good against evil. The fate of the Big Blue rests with Gray!
