Liked this book and the fact that it stayed focused on basically the work of Lucas throughout. The story was streamlined in a manner that I felt made it easier and more enjoyable to read. I did feel that chapters 8, 9, and 10 had a pacing issue and were a little choppy when reading; but it did not significantly impact my enjoyment of those chapters.
I do hope we get some further look at the actual life in space; that said, I hope we also get to keep up with what Lucas is doing and how he adjust to being back basically as a resident of Earth. What happened with his family, did they come with him?
