Books & Beyond discussion

I think, like a lot of people, I judge a book by its cover. If the cover looks interesting, I'll read it. I also read the title--if it catches my attention, I grab it off the shelf and start reading the back cover. Does anyone else get mad when a book cover doesn't tell you what the book is supposed to be about? I generally put it back on the shelf if it doesn't have a summary on the back. Though it's easier now with goodreads--you can look it up and see what it's about.
