I haven't read any of the reviews and honestly I don't know why anyone would give this book less than 3 stars, but everyone has different tastes I suppose. 
 This was a really good book in my opinion. It was action pack, and funny even when it wasn't suppose to be. I guess the fact that the story ended too perfectly could've been a thing that made a lot of people upset, but I felt like with all the war and death that was going on the happiness was needed. 
 I don't say this because (Spoiler alert) I like her and Mal together. I hated Mal a lot! He didn't grow on me in this book at all, he lost all my respect for him two books ago, but the life they created after the fighting was kind of fitting. Even thought I felt Alina's attachment to Mal was too much at times and I wanted her to get the hell over it. It made sense. I'm sad I finished these books so quickly because I really did adore this series. and the four stars were well deserved. 
 the whole series is like a 4.5 star rating and I'm sure I'll read it again.
