" This isn't your average book, it's pure gold: Twelve Fail-Safe Ways to Charm Witches. Explains everything you need to know about girls. IF only I'd had this last year I'd have known exactly how to get rid of Lavender and I would've known how to get going with... Well Fred and George gave me a copy, and I've learned a lot. You'd be surprised, it's not all about wandwork, either. "
