I more or less feel the same toward the second book in the series as I did toward Divergent. It felt too rushed a lot of times and could have been done differently. I felt that the writing was lacking in some places and more could have been added, not in the story, but in the telling of the story. I did feel that it was slightly less rushed and flowed a little better than Divergent did however. A couple of things that bugged me with Divergent were also lesser in this book. All in all, I think I liked this one slightly more than the first. If you read Divergent then you definitely need to continue the series.
Expect an Allegiant review in the future.
