This has never happened to me before. Even if a cover was "meh", I still gave that book a chance. But here I am, choosing not to read a book, just by its cover.
"Never judge a book by its cover." We've all heard that. Unfortunately, most of us do it anyway. Covers are the first thing that draws our eye. They're the first thing that we see, the first thing that makes us think: Huh, maybe I should check this book out. No matter if the book is good or not, we still judge the book by its cover.
There's even memes like Lusting for Covers by The Book Queen, where they feature a great cover or Cover Wars by the Book Whore, where they vote for the best cover.
Covers are essential to the promoting of a book. There's been times where a book has gotten a new cover after a while of it being published. Most self-published books don't have awesome covers, because they don't have artists and the resources available to publishers.
So now it's your turn. Has there ever been a time where you didn't read a book just because of its cover? How much do covers play a part when choosing whether or not to buy a book?
