This book held my attention more than any book I've read this year--absolutely gripping, haunting, chilling, lots of -ing verbs that add up to a truly incredible reading experience. The characters are beautifully drawn and the elements of magical realism totally pulled me under; it's hard to know what's "real" in this book, harder to care. Impossible to describe, clearly, but if you like sister stories or horror-flavored YA or magical realism of just gorgeous writing, you must try this book. I'll not stop thinking about it any time soon.
