Zak Nine and his friend Erro are on the run! While avoiding a band of patrolling prison guards, the boys meet another escapee who tells them the legend of an abandoned spacecraft. The boys believe that if they can find the ancient ship, they'll be able to fix it and blast off from Planet Alcatraz. But first, they must cross the Igneous Quag, an uncharted swamp full of flame-spitting snakes and hidden geysers of fatal fire! Part of the Escape from Planet Alcatraz series.
