"Everybody" knows who Larry Niven is, but Brenda Cooper?
Who cares, this is a really good story, strong characters, great technologies.
A group of professionals leaving an AI/nanotechnology overrun Earth in a huge slower than light starship the John Glenn. The first of three heading for a planet Ymir. But the John Glenn has a design flaw and is nearly destroyed. It signals the problem back to Earth and then has to find a stellar system to divert to to make repairs and refuel.
The subsequenty story is about the task of surviving and building the resources/equipment to get the John Glenn to Ymri, but there is human conflict. To give more detail would spoil it.
Read it! One of the key perceptions of a good book for me is, do I want to read more. And I do! What happens next? I must know!
