I hate to say it, but I'm one of those people that judges a book by it's cover. If the cover looks cool, chances are I'm going to pick up the book and read the back of it. If the back sounds good, I'll definitely buy or borrow it. The kind of covers that make me pick up a book are the kind that stand out. It's got to be colorful, but not too flashy. It's got to make me wonder what the books all about. The 100 Cupboards series does exactly that. Don't ya think?
