update: I'm thinking back to this book and I now realize that it wasn't that great, but at the time I enjoyed it but now ... I'd probably give this like 2 or 3 stars but I'm going to leave my original rating up. 
 Great book the plot twist got spoiled for me which sucks but I love fantasy books and this is definitely one of my favourites. I can't wait to get my hands on the next book. I can practically hear it calling to me... 
 Hehe this is an updated review because my last one wasn't actually a review and basically just me dumbfounded and shocked freaking out because this book was just that good. 
 Ok, I give this book a 4.5, it was amazing. We follow Mare, Mare lives in a world where people are divided by one factor, the colour of your blood. The red bloods and the silver bloods. The red bloods are like you and I regular people and they are the peasants in the kingdom, they make little money and don't live in the nicest conditions. But the silvers live like royalty, they each have a different power making them stronger than the Reds, the slivers are the rulers and make up the monarchy. You have a chose when your red (well not really) but you either get a job before you turn 18 or get drafted to the army to fight against other kingdoms like this one. Mare is a red about to turn 18 with no job yet and already certain that she's going to the army just like her brothers and has completely lost hope in finding a job. But she gets lucky and lands herself a job as a servant in the castle for the silvers. A lot goes down until Mare discovers that she has a power too, a special power, that not many slivers have, even though she is a red blood. 
 I had a lot of fun reading this book and fell in love with the characters (there are some pretty hot princes in it). It surprised me in places, made me hopeful for something's to happen, it made me laugh and angry in some parts (really angry). The book is really well written it makes you keep wondering what's going to happen next, the storyline was great lots of ideas incorporated and always something going on so that you are never bored, this is the kind of book that you loose sleep over and won't be able to stop reading even if you want to. 
 The plot twist was pure genius, you grow connections with characters, even all the secondary characters you end up loving. The characters all gain your trust until it turns in an unexpected direction and you end up throwing all that you thought under a bus with nothing left but a blank sheet to start all over again and a brain that feels like mush. 
 I have read a lot of books like this one but I never get tired of them, I recommend this book all the way, if you are into high fantasy, love a good mind blowing plot twist (that even coming into the book I knew about, it still managed to blow my mind and make me want to pull out all my hair), with great strong characters that you will fall in love with, then this book is for you.
