Heh. I've gotten pickier and pickier about certain elements that I do or don't want in books lately... which is why I've come to rely very heavily on recommendations from friends and/or checking things out closely beforehand. In many cases I'd rather get spoilers but know there's not going to be something I'll hate than go in blind. Annnd also why I've come mainly to buy books that I already know I love, rather than buying it before reading. :P

On the reverse, I have read books because they came highly recommended which had such awful covers that I probably wouldn't have picked it up otherwise. (Part of the problem is that the author generally has almost no say in the cover design, and much of the time the artist doesn't have a chance to read the book beforehand, or even have access to good descriptions. Not logical, but there ya go.)
