I read this a few months ago, actually, so this review's late. But now I'm reading the sequel, and I happen to have some free time, so I'm finally getting around to it. :)
I really like this book. It's mostly based off of the frog prince fairytale, but it's got a lot of other fairytales mixed in, which is cool. The writing is awesome because it has a fairytale-like way of saying ridiculous things (like people turning into animals or people climbing giant beanstalks, that kind of thing) that makes it seem perfectly normal. I wish all fairytale style books were written like this one.
The main character's a nice, dreamy/creative/absentminded girl that also fits well with the fairytale theme. The other MC, the prince, I also like--which is rare. Oh, and I also love the fact that he doesn't just appear in a flowing cape with his hair already styled perfectly, ready to carry away his princess, when the frog prince turns back into a human.
I'd easily recommend Enchanted to any fairytale-loving person, and I'm really glad I read it. It surprised me, which is always--well, a surprise. XD
