In the beginning of the book, we're in a middle of a forest, which is catching fire. So, we see a boy in the middle of the trees, but he start to turn, we see that was just a dream. This is how we're presented to Clara, a quarter-angel, who lives with her mother and brother, in California. 
 We can see that this history starts a little different than the usual. In this history the protagonist already knows that she's a part angel, instead of discover that she's not totally human during the book. And instead of other books, this books don't focus only in Clara's powers and their development. Cynthia Hand knew how to mix Clara's development as a angel and her relationship with her family, friends and love interests. Clara has two love interests during the book: Christian, who is the same boy who appears in her visions and Tucker, her friend cowboy brother (I even wrote a "My Book Boyfriend" about him! Read here). When you get the book, you can think that you know the end, but the author knew how to make surprises. 
 Clara was annoying and selfish sometimes, but we can forgive her, because at least she knows when she needs to apologize. 
 Another thing that I liked in this book was Cynthia writing. I really could feel Clara's emotions. I could feel when she was sad, happy, worried or in love. I don't like books in first person, that i really enjoyed this one. 
 The only that I would change was the appearance of her family and friends. Some of them appeared so little that, I couldn't decide if I like them or not. Clara's brother was one of them. 
 So, in the end, this is a book which i'll buy when i get the chance, because this book I'll read a lot of times more! I really enjoyed this book!
