I sooooo wanted to love this one. It started off so strong. Dean is a master at building tension. The repetition of certain aspects of life in the chamber started to feel redundant but it was a master tool at making the reader feel just as claustrophobic and trapped as the characters. The first half or so I was all in, and couldn't read fast enough. By about 3/4 of the way in, I was starting to have my doubts about how this would wrap up. And by the end I was just so unsatisfied. There was too much ambiguity for me, and I wanted to know more about what was happening outside of the chamber. However, Dean will continue to be an auto-read author for me, he's incredibly talented at building a world that draws the reader right in.
