Wow. Just wow. 
 I have a hard time even coming up with words for this book. It's not like anything else I've ever read, especially in the YA genre. It is dark and violent and wrenching, and also ultimately beautiful and hopeful. I stalled out a bit in the first few chapters because it was so bleak and I didn't know where it was headed, but it picked up once Wasp's story intertwined with the ghost's, and I absolutely devoured the rest. 
 Dark and lovely and well worth reading.
