Temozar Alkabah, Artemis Katsaros, and Mingus Twombe have their hands full, dealing with an unruly population of refugees from the Khaozian destruction of Earth Three. Mingus, the military genius, organizes attacks against the rapidly increasing hordes of land sharks, only to discover that Khaozians have already landed on Eden, and are hiding in the subterranean land shark dens. Among the refugees from Earth Three is Drew Harrington, noted exobiologist and Temozar's long lost friend. Drew and the Korean scientist, Ae-cha Kwon, come up with a possible biological weapon for use against the Khaozians. Temozar appears to have turned against his own kind and gone over to the Khaozian invaders or has he?
