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!
John Peel is the author of Doctor Who books and comic strips. Notably, he wrote the first original Doctor Who novel, Timewyrm: Genesys, to launch the Virgin New Adventures line. In the early 1990s he was commissioned by Target Books to write novelisations of several key Terry Nation Dalek stories of the 1960s after the rights were finally worked out. He later wrote several more original Daleks novels.
He has the distinction of being one of only three authors credited on a Target novelisation who had not either written a story for the TV series or been a part of the production team (the others were Nigel Robinson and Alison Bingeman).
Outside of Doctor Who, Peel has also written novels for the Star Trek franchise. Under the pseudonym "John Vincent", he wrote novelisations based upon episodes of the 1990s TV series James Bond Jr..
This story was just great and actually made a good deal of sense throughout. With all the adults gone, the kids manage to cope under the supervision of the intelligent computer. Some shrewd kids, I might add. Lowering the marriage age to thirteen is hilarious but also makes perfect sense. One character makes a comment that pacifism is a two-way street. Overall I thought it was an excellent, entertaining story that made sense, was realistic. The author handled things well and didn't resort to some silly, dumb cop-out, but captured the reality of human beings.
