I learned about this book from the blog of one of my favorite author - Richelle Mead. Once she recommended to read "The Morganville Vampires" series and I liked it very much. So when she wrote about this new book she enjoyed, I decided to give it a try. And I wasn't disappointed not by Ms.Mead taste and not by Ms.Hand writing. 
 In the last couples of years the amount of YA fantasy books has grown really high. But only a few of them is worth reading. The larger part of this books authors fill with what they think teenagers are looking in books: first love; school; prom; common main heroine (not beautiful, but suddenly all boys star falling for her), who is longing for some cool and beautiful boy , who is so out of her league. And when I read this books, I don't feel a story, all I could see is an author who tries to make money by retelling "Twilight" only with other mystical creatures. 
 Well "Unearthly" is one of this rare good YA books. It was very easy to read, characters were realistic and didn't annoy me with their behavior and choices. Romance was not some pink snivels (is there such expression in English?), it was cute and believable. One thing that I didn't like was that book is written is present tense, but I stopped noticing it after awhile, which means that writing is very good (because I hate present tense!) 
 So, if you are thinking whenever to read it or not, I will say: Stop hesitating! Read it and you won't be disappointed.
