Entwined was a very nice and easy-to-read book. It took a while to really take off, but the beginning wasn't boring, either. It was kind of odd in that it was cute but dark at the same time. The beginning of the book is, of course, setting up the story, and revolves mostly around the twelve princesses and general life at the castle, and coping with the recent death of their mother. Even though it sounds slow, the princesses are all fun and have a sense of adventure, so it works. Mercifully, the author decided to name the princesses after flowers, in alphabetical order by age. (Azalea being the oldest, then Bramble, then Clover, etc, all the way down to Lily, the youngest.) This made them SO much easier to keep track of, and easy to quickly figure out how old any one princess may be. This was a total lifesaver while trying to read the book! Even with so many characters to keep track of, the author does a great job giving each their own personalities. The older sisters are fleshed out more, with Azalea, Bramble, and Clover in particular having especially likable personalities. The younger sisters aren't developed as much, but that works out well because it keeps the story from getting too cluttered. 
 Although the quieter beginning of the story is nice, once action starts to pick up, the book is really hard to put down! The villain is entirely creepy (and is likened to a large black spider more than once) and manipulative. The dark acts he's capable of are a shocking contrast to the sweet innocence of the princesses. 
 Of course, you can't have a YA story with TWELVE princesses without having at least one love interest! Enter our hero, Mr.Bradford. He's one of those sweet, lovable, all-around good guys. There's nothing particularly remarkable about him, but he doesn't have that "Gary Stu" vibe either. It's actually really nice to have a break from the sarcastic bad-boy types that are becoming so prevalent in YA books lately. For a book about fairytales and princesses, though, it's not overly girly or sappy. There's just the right amount of romance for the story, although it's very innocent and chaste. 
 The only real issue I had with the book was the bit at the end with Fairweller. I couldn't figure out why all the characters were overreacting so much. Maybe there was something I missed...? 
 Overall, Entwined was a really nice, solid read. Don't expect anything too out of the ordinary or complex. This is the first retelling of the Twelve Dancing Princesses that I've read, so I don't have anything to compare it to. I have read the original fairytale, however, and thought that this retelling did an excellent job of preserving enough elements from the original story while adding enough to make this story stand on its own.
