I am only taking one star off because because I now have to wait like 8 months for the second book and over a year for the third book to be released! I loved this book and cannot wait to read the next installment. Any time you read this type of dystopian novel you have to be a little wary of is this going to be a knock off of some of the other successful dystopian stories but this was most certainly it's own story. It was exciting from start the finish and while it covers a large period of time, it doesn't feel that way. I like the premise of the firstborn and secondborn and their roles in society. Where in other dystopian worlds you have two individual classes, here you have two classes in a single family. I will definitely be reading this again prior to the release of the next book.
