Actually, I don't think that's one with lesbian characters. I'm not entirely sure, but I think they really are just friends. Still a good choice, though! So I went compulsively go through the list and added all the GLBT ones to my post. Heh. There are twice as many gay titles as lesbian, but that's more indicative of what's out there than anything else. And thanks for reposting the links! *hugs*

Sometimes you can find booky icons on book_icons, though a lot of them are based on specific books. I've snagged a bunch of images from the New York Public Library's Digital Gallery, which is truly amazing to browse through.
