I don't read a whole lot of sci-fi, but I don't want to find myself stuck in a rut either, limiting myself to only one of two genres of literature. So I try new things occasionally. I read sci-fi a few months back, when Felicia Day's "Vaginal Fantasy Hangout" featured two books I hadn't read before. They were more to my taste than this, which turned out to be a bit to spacey for me. I didn't hate it, by all means, but the story didn't really grip me either, and I kept making myself go back to the book to get through it. I don't like it when reading becomes a chore.
There's some very cool world building in this book, and the characters are nicely multi-faceted, it's not quite clear who's right and wrong. The story is told mainly from Holden and Miller's alternating POVs, and for the first part of the story, they're in very different places. There were some very cool concepts in the book, and certain sections are rather horrible, but creatively speaking very well done. While this book just doesn't seem to have it done it for me, I can see why it's popular, and why it was selected as a monthly pick in the "Sword and Laser" book club.
