** Slight spoilers **
If you haven't read Reynolds before, start with one of his other novels. If you are a bit of a completist like me, then give it a go. The novel is very good, without reservation, up until the exiling. I fast-forwarded through the character problem bits after that, but I wouldn't recommend actually skipping chapters, as there are still a lot of good ideas to be found in it. I wouldn't be averse to a sequel, as the character problems are moot by the book's end, and the universe of the book is well worth further exploration.
