Query: Disgusting Book! Do not read!

Don't read this book unless you want to puke for the rest of your life. I wish I'd never read it; I tore my copy in half and threw it in the dumpster. If this story became a movie, it would be rated X. If you want to read some good Orson Scott Card, read Pastwatch.
