I've been meaning to read this forever (for a given definition of the term) and then it was nominated for the Hugo, which made me incredibly happy. The thing about Valente is that, while she has a distinctive touch, very few of her books are exactly the same. And so this is not like her lush adult fantasies or like her gorgeous take on children's' stories. It's a thing of its own; a retelling of Snow White set in America that is both entirely true to the fairy tale and completely redefines it for the audience.
Perhaps needless to say, I really liked it!
