School's out on the planet Tarshish...forever. Humans have established a thriving colony on the planet Tarshish, until a native species of semi-insectoids awakens from a long incubation and attacks the colony. Only the children survive--and a computer. The computer teaches the children how to form their own community. A community without adults and without boring adult rules and stupid adult regulations. On Tarshish, kids rule! Until the day a rescue ship arrives to bring them back. But the kids don't want to be rescued. They like being in charge. In fact, they might go to war to prove it!
