I overall loved this book, although that wasn't my original opinion. I started reading Incarceron in 7th grade, and was as confused as you can get. Anyway, NOW, I'm 19 and I loved the characters, the plot, the journey, and the sequel. This book and its sequel are great for people who like dystopian novels and/or science fiction. The only people who might NOT like it are particularly religious people of all backgrounds, or people who are underaged. The characters are interesting, as are their relationships. To sum up my review, I couldn't wait to read Sapphique, and when I finished Sapphique, I was wishing there was a third installment.
