Have you ever bought a book because you liked its cover art? -Billy @ Coffee Addicted Writer
Of course I have!
Haven't we all?
The first and only one I remember was some Nora Roberts book. It was greatly against my better judgment given my general aversion to romance novels, but it had glitter on the cover and claimed to be fantasy.
I don't even remember what it was called (it was a series of short stories), I just didn't like it. And it was technically fantasy. It was just fantasy with a complete focus on romance.
There have been others, but that's the only one that sticks out. Covers are pretty amazing these days, much so more than I was a kid/teen/young adult.
(Of course, the terrible covers are a million times worse than they used to be.)
