Although I do not write many reviews, this book needs one. There are a few things the author did well, but there are other areas where Marie Lu needs improvement. I am a terrible writer (it's easy to tell), but I'll do my best to express what was great and what was not so great. 
 The Great 
 It is always nice to begin with the best news, right? The book did do it's job in capturing the reader's attention while not including too much fighting and action. The plot details, characters, and suspense are enthralling. I was simply unable to put the book down, despite it's annoyances. It was a satisfying end to a good series, although not as well written as the books before. I must, however, give credit to Marie Lu for the ending of the book. However, it would be so rude to spoil the ending so the dreaded tags must be used. Click at your own risk. (view spoiler)[The ending cannot exactly be defined as a "happy ending". Yes, the Republic and the Colonies stopped fighting. Yes, they are both better places to live in. Yes, the important people are still alive. Yes, the public still loves Daniel. But if it just ended there, the story would be too unrealistic, right? So the author, being a good one in this respect, added a few not-so-good things. Day lost his memory of his years with June and as a result June became closer to Anden, instead of Day. Then there's also the small fact that the Republic lost some of it's land to Antarctica. The ending is balanced, which I enjoyed. (hide spoiler)] 
 The Not-So-Great 
 I have not had a chance to write this. I will soon, though.
