A very interesting book! I really think Fisher had amazing ideas and did a pretty good job at executing them. The writing was done in a way where you could image the Prison's scenery vividly. The concepts for this book is mind-blowing! I absolutely loved it! The characters, however, are the weak point in this book. None of them are that amazing and some of them you just want dead *coughKeirocough* but others are great! Jared and John Arlex and Attia are pretty good characters~ I have a soft spot for them. But the others... bleh.
Anyway, this book isn't for everyone. It's to my knowledge that not a lot of people understood the plot or the point to it all. However, I had no such problems. I enjoyed it well enough and I think if you want to read something that is extremely different from other books, then you should give this a read. It's pretty good and I am looking forward to reading Sapphique.
