First book of a fantasy duology, this novel is such a big improvemente from Anna dressed in blood. I read this book in November and I cant definitely says that it's one of my fav reads of the month and the year, even with its flaws. I siply couldn't get enough of it. I wanted more. And I will die when One Dark Throne will come out. 
 Honestly I have problems to understand people who complain about how the book is slow. Yes, it's, I don't deny it, but this "slow thing" has a point, since it's quite a political book more the none of action. Plus, some books, if you want a richi plot and vivid wordl, needs time to develop. That's why I never ever put a book down until the end. You never know. And that's really true for Three Dark Crowns. In fact, if left this book unfinished, I think you missed an amazing ending. 
 The novel is set on an Island, where every generation a triplets of female is born. The queen left the Island but the triplets have to say and their destiny is to kill eachother until only one is left. And thi one will be queen, obiviously. Every queen has a power, but this generation is quite peculiar.... 
 As I alreasy wrote, this book takes all its time but if you love twiste and cliffhangers, that's quite a read for you. If you're searching for smart male characters, you aren't going to find it. The Island is a reign of women. I quite like this thing, even if I didn't appreciate most of the female character - they're to bitchy and cruel for no reason - this book also gave me some great and strong character. Another thing that was so-so it's the romance. I don't really feel the connection between the characters - but I'm kinda of aromantic, so my opinion is always really realtive - and at some point I just find it nosensical. But at the same time it doesn't seem forced, which was great. 
 But, anyway, romance isn't the centre of the plot. It plays a great part but just as a way to make some things happen, so it's actual funciton only depends of the direction of the plot. 
 The three queens are really different between eachother but it nearly took me no time to like more Arsioneo above the others two. I think she was the moste genuine - even if sometimes she fuck ups thing in a really stupid way - and always trying to make things right, even her own mistakes. 
 Katherine as the one I liked less, and I really don't know what to think about her. She seems quite sadic and comments about her sisters in a way that makes no actual sense. There is something really dark in her, and even if this kind of character maybe is the most interesting, in the end I never managed t like them. 
 Mirabella was on my top list for a big parte of the book. She is the only one that is trying, or tired to under stand thing, the only one that talks about some secret that she and her sister whispered in eacother ears when they were little, the only one who wants to put a stop. And then she acted like a totally dumb idiot, following her insticit like an animal - you know, one of humans quality must be autocontrol. In the end, she thinked with her ass. 
 Until the end I hoped fot things to start working right for the sister - happy ending fan right here, or at least what can be less painful - but of course that didn't happen. And don't even try to tell: spoiler! Beacuse it was relly clear from the start that eveything was going in that way. It's just me. I'm an enternal optimistic that know that thing will go really bad. 
 One last thing and my review will be finished. The world. I really like it but forget that the story and the author will come next to you and guide around the Island. Names, descriptions - use the map, which is draw in a really cool style - and everything else is dropped alla round the story, so while the plot goes on the world do the same thing.
