This is a book that says as much about humanity's regrowth after the Dalek invasion as it is about ecological protests against corporate greed. The humans are a bunch of rabid xenophobes you'd want to shoot rather than share chromosomes with and the greedy corporation of Dreamstone Inc is even worse. The Doctor and Sam almost run into each other a couple of times, narrowly avoiding each other a few times, which is a good thing as it builds tension and teases the reunion. New temporary companions Daniel and Aloisse are interesting, he's a jaded miner who only cares about providing for his family and she's a radical protestor who falls foul of the humans and suffers terribly at their hands. The premise of the story is pure Star Trek, alien moons coming to life, but there's a fresh Aliens twist as the military boot lands heavily on the situation.
