I was thinking about why I by a particular book over another of the same genre. For me, it used to be the author until such time as I had all of a particular authors work. Then it changed to reading the "hook" and with the cover art being last. Don't get me wrong, cover art is the coolest, but the buying a book just because the cover is cool doesn't quite work. It is a factor, though. So, what do you think?
