Covers are either pretty or just there. I'm more interested in the author and the storyline. And, yes, I get very upset when the people on the cover don't match their descriptions!
I've not read The Secret Life of Bees. I love Grisham's books. I didn't have a problem with The Client or the Pelican Brief. I did find fault with The Firm. Hated the movie but loved the book. I try hard not to compare books and movies. I'm usually always disappointed or upset or both.
