I finished the series. At last. But I got to admit I was disappointed in this one. 
 So far Winter has become my favourite out of all four. She's just so unique and hard to hate. In one word she's amazing. If I had to chose a MC to be in the series I would gladly choose her. But something about the story just didn't go well with me. Compared to the other three I did not like this one as much. 
 As usual I found Kai annoying and stupid, Cinder super cool, would love to have a best friend like Cress and Scarlet, of course Thorne too, completely swooned over Wolfe and had mixed feeling about Jacin. I liked how the characters stayed the same thoughout the series, most of the series it doesn't happen. But the story fell flat compared to previous ones of the series. But nonetheless it was an enjoyable series and I would like to recommend it to anyone easily.
