I thought this was a definite improvement over Pure. I was pulled into the story very early on. This book really has it all with great character development, good plot, interesting and thought-provoking themes, and great descriptions of setting. I especially enjoyed Baggott's descriptions of the world and the people in it. You can really see it in your mind. The fusing aspect can be a little disturbing and hard to believe, but I like it as an interesting and original part of the series. I look forward to the conclusion to this trilogy.
