Description
They call them the "rat-catchers." They're the crew of the spaceship Daedalus, which an economically destitute Earth has dispatched on a mission to re-establish contact with its far-flung, long-lost colonies in space. Alex Alexander, the ship's biologist, together with his staff, must help solve the mysteries of human and alien ecosystems that he encounters light-years from home. Dendra is a stable world, covered by a huge, unchanging forest?except that nothing living can really be free of show more change. The planet has no seasons, but its animal life still undergoes life-cycles involving birth, maturation, metamorphosis, and death. The Earth colony sent to tame the world has failed, at least in the terms expected of it, and seems beyond redemption; but the crew of the Daedalus still has to find out exactly why and how the program has gone wrong. Provided, of course, that they can survive the investigation itself! show lessTags

Thoughtful to a fault. This is the second entry in a Star Trek style puzzle series. Some elements of Earth's government want to restart extraterrestrial colonization after a long hiatus. Unfortunately, an expedition to several prior colonies found only disastrous failures. The Daedalus has been sent to visit another set of colonies. Their mission: find some successes or at least find explanations and solutions so that colonization can resume. Each book is a different colony and a different puzzle. In this case, the crew finds a small group of descendants still alive but just barely subsisting, child-like in their ignorance. What happened to the colony, and the role played by a heavily forested planet with no seasons is the heart of a show more plot very similar to the kinds of tales James White liked to tell in his Sector General series. Unfortunately, Stableford wants to make it all mean something bigger, so long after the puzzle has been resolved, the main character reflects on and on about life in general. show less
A bit dated.
