The Normal Heart is close up there, too, but I don't think I'd necessarily have gone out and read it if I hadn't seen the play, so I don't know that it really counts. As for actual book, I'm hopelessly in love with The Picture of Dorian Gray. I have no idea why.
oh, and Delph... I like Perestroika better, I think. I tend to forget what happens in which one. It kind of depends on the day. They're so different. And yes, you do that running. The Normal Heart is one of my most prized possessions. I think I've read through it something like thirteen times. I don't think these boards knew what to do with me when it closed.
