You know...the ending just wasn't as satisfying as I had hoped. Incarceron was like this, too. I don't really like the cliffhanger/unresolved endings, but was okay with it sliding from Incarceron to Sapphique, but the ending needed more. I needed more of the world, more of the changes within Incarceron and Outside to be resolved. More of Jared/Sapphique and Incarceron working together with the Warden, etc. Overall, enjoyable. Not sure it belongs on my rereadable shelf yet.
