Highly recommended that you read the prequel first.

Clovenworth Prison has been regarded for years as the most escape-proof facility in Equestria. Layers upon layers of both physical and magical security, a troop of well-trained and equipped Guards, and three miles of stormy, choppy sea separate the worst of Equestria's criminals from the rest of the country.

Until Zugzwang entered the walls of the Prison. Within hours of his imprisonment, Zugzwang successfully stages a mass breakout and overtakes the entire island, leaving Phillip Finder and Shining Armor trapped with an army of bloodthirsty criminals. But there's more to this plan than just a breakout attempt.

With aid from Flash and Twilight, can Phillip and Shining band together to stop Zugzwang, or are they doomed to die in Clovenworth Prison?
