Necessity

...On the whole, I don't think Walton finishes the trilogy as strong as she starts it. It is not a book that adds that much to her vision of Plato's republic. I enjoyed reading it quite a bit but not as much as the previous two volumes. As a whole, the trilogy is a work to remember though. Walton takes on complex subjects and ideas in these books and yet manages to keep them very accessible. I would not be surprised to see a few people pick up some of Plato's works (note that Walton does not recommend starting with The Republic). Walton pushes herself in these books but she also pushes speculative fiction as a whole in a new direction. There are not many authors that can claim to have done that. Maybe she falters slightly on the home stretch but it is still a noteworthy work of fiction. I recommend you read it.
