2,5/5 
 Warning : The first part of this review is spoiler free but the last paragraph will have spoilers in it 
 This book... Is kind of a very pretty empty shell. 
 The story by itself is interesting and pretty and enchanting and there's good ideas along the way. 
 However... 
 - The characters are the least developed characters I have read in a very very long time. Especially the dragon, but no character is immune. They have one or two traits of character, specified when they get introduced and that is it. They were never really alive thought those 435 pages... 
 - The magic system doesn't make any sense and has no explanation whatsoever. And the problem is, as there's no explanation, it sounds like the author can do anything she wants, just when it serves her story, thus enforcing the feeling that the characters are just puppets, that just do whatever she wants in order to get to a point. 
 - if you dislike the trope of the main character that can do a lot of things that no one else has been able to do in centuries and with only 2 days training... Do not pick up this book 
 - the love story.... I... Can't. This will go in the spoilers section below. 
 So basically the world itself is great but the characters living in it and everything around them... Is really really not good and that doesn't make for an enjoyable read. 
 /!\ Spoilers below /!\ 
 So first either there was a writing problem or I missed something but... Could the dragon read agniezka's thoughts ? Because a couple of times, there was a descriptions of her thoughts as it is first person... And suddenly the dragon would answer those thoughts but there was never any mention that she had said any of those things aloud... It threw me off (not really spoilery unless I really missed the fact that he reads her thoughts, but I doubt it) 
 The love story : what the hell ? The dragon is barely alive in this book, so it doesn't help but agnezka (who should be a little bit more fleshed out as she is the narrator... But isn't really) seem to only think of them together when they are actually kissing. There is no mention what so ever of her feelings for him at any point outside of those moments. She never thinks about it, she never miss him, she never mention him... How are we supposed to believe anything is happening ? First they kiss out of nowhere and then she just dismiss the age problem with absolutely no argument (the author probably didn't want to have to deal with the problem so agnezka dismisses it and that is it ?! Ok I know since twilight (and other vampire stories) problematic relationships are sexy... But at least try to argument your reasons when you make a sex scene between a 17-18yo and a 200yo.... 
 I need to go read something else.
