Maybe 3.5 stars.. (you know how stingy I become when it comes to giving stars!) 
 [?]Likes: 
 * Storyline (Except for the book four, it was exciting and complex enough) 
 * Characters (I loved Cress! Plus Thorne and Winter. Even though all the rest had the same personality, as I said in my review of Scarlet) 
 [?]Dislikes: 
 * False Thrilling (there's this thing that happens many times in this story, that someone knows something and if [s]he tells someone else, the problem will be solved. But [s]he just decides not to tell anyone for no reason until the problem grows into a disaster. It's kinda annoying) 
 * Book four! (It should have been gripping, but no. It was boring. Events should have happened real fast. They were just walking around the corridors and walking and walking.. what kind of a palace is that?! Where are all the soldiers?!) 
 * Fight scenes (too confusing, too slow, forgetting about other characters around..) 
 * Cover (it's just that, the Cinder's cover was so good that makes any other cover a disappointment!) 
 P.S: Everything else was normal, not so good or so bad, e.g. writing style or atmospheres, so I didn't list them. 
 P.P.S: It was the first story to point out that people sometimes need to pee! And it's sometimes not as easy as it sounds like!
