Personally I would have enjoyed this book more if it had addressed the time the author intentionally skipped. It might make it easier to understand what was happening. I enjoyed this book a lot because the character development was amazing. The author did a great job describing the changes gradually. She also did a great job with the plot. There were no plot holes and it seemed to flow well together.
