***WARNING*** Spoilers towards the end of the review!!! 
 Wow, what a book! I'm usually pretty good at picking out things I think I would love, but lately it seems I'm brushing over things more easily than I used to, and am blown away more often because of lower expectations. Not necessarily a bad thing, I guess. And I seem to be reading a lot of books with people named "Eva" in them. First What's Left of Me then Bared to You and now the Lost Girl. Hmm. 
 I absolutely adored Eva. Even though she was forced to copy someone her whole life, even though it would have been so easy for her to be a quiet, mellow little protagonist, she wasn't like that at all. She stood up for herself when she needed to, she didn't hesitate in trying to find ways to stay alive throughout the story, and was intelligent and quick. 
 The situation between echos and their others pains me, because I can really understand both sides. In this case, I disliked Amarra, but at the same time I could understand where she was coming from. To know that someone is going to completely take over your life once your gone is very scary, and not something I would want. In her shoes, I might not be the most polite person to my echo, either. Still, since Eva was telling the story, I still cultivated a strong dislike. The same goes for Ray. Even though I really felt sorry for him and his loss, his actions in the book made it hard to like him overall, in the end. 
 All the characters were well thought out and brilliant in their own way. The Weavers were very interesting to learn about. They were the villians of this story, but perhaps there are bits and pieces of good scattered throughout them. Maybe their intentions were good to begin with, but everything in their Loom has become a dark, twisted place in some respects. The way they play with life and death is downright crazy. The other characters, too, Mina Ma, Erik, Ophelia, Lekha, Nik, Sasha and all the others were all such good, interesting people. 
 The romance is between Eva and Sean. I refuse to count Ray as a love interest, because he was only ever with her for Amarra, to see her face. It was very sweet, and, even though I sometimes resented Sean's refusal to break the laws in the first half of the book, I understood why it was necessary. 
 The writing is gorgeous. It's very easy to go along with and thought provoking. I paused multiple times while reading to simply take in what had just happened. The little stories about the mongoose and the little ducks were sad on their own. But Eva's own inner turmoil, and the grief of Amarra's boyfriend and family, was heart-wrenching as well. 
 My only complaint is the ending. I felt like the book could have used an epilogue maybe a few years into the future to see how Eva has settled back into life after leaving the Loom. I still don't totally understand why Amarra's parents were willing to take Eva back after signing the Sleep Order. And I would have liked a runion with Sean, since their last real encounter in the novel left on a somewhat sour note. 
 Despite my one issue, The Lost Girl was still an amazing story that gets 5 stars from me.
