This was the bookgroup book this month and going by the emails, most of us liked it okay. Not dramatic, but not bad, either.
The world is making only clone groups now and our protagonist group (considered one person), Apollo Papadopolous, is a five-clone group and very rare. They train and during their training, they frequently come close to dying. During their time on a station, they find out that a duo is trying to kill them and they get to the Ring. The Ring was built by an earlier generation that left lots of dead people when, theoretically, their spirits left for space. The Ring has an AI that helps the clones get back to Earth, but again, they're caught. One of them is able to almost kill the duo and let someone else take them.
The planet's Over Government swears the duo wasn't part of them. Then the OG asks them to find a Ring participant for them. He'd been in freeze mode when the Ring people "left" and when he woke up, he started making more Ring people. The clone group finds him and he chases them. They manage to get into another link to the Ring and find that a new AI would like them to join it so the Ring could be populated again. What do they do?
When I started this book, I was sure I'd read something like it -- where clones on the Moon kept going back to Earth to try and make it habitable again -- but it wasn't entirely like this one. I thought maybe it was a smaller part I read somewhere, but it's not noted in the front of the book, and I didn't find it in ISFDB. Any ideas?
This book starts on Earth where a man is trying to set up a colony on the Moon. They have three big rocks hit the Earth, the last one big enough to kill everybody, so his specialists, and a man who points a gun at them, makes it onto the spaceplane and up to the station. The robots make clones whenever they think something can be done to help Earth. At first the clones are very stupid and get killed, but there's history of what happens and later clones are not as bad. They meet aliens, humans who don't believe who they are, a colony made by earlier clones that now has slavery, etc.
A set of clones wake up with Uncle Pen, who is smaller, has internal sex organs, and brown fur on his head. The Moon had a rock impact that covered over the station. He dug it up and made a big project for his world government. The clones don't believe that they were made just to be a reminder of how the station was, and three of the guys follow Pen back to Earth. It's not at all what they think, but their differences from the new "humans" allows them to solve problems.
