I've read all of em! Most of it nude, except for the sections I read on the subway or in a cafe, haha.
I think they are really cool. Not my favorite books. I do feel like watching the movie made the book better (for some reason it was hard for me to imagine things, so in that way the movie was a great addition). I'm excited for the second movie to come out.
When it come to reading nude, it's not really different than reading any other thing in the buff. Except for repressing boners when Katniss and Peeta make out. JUST KIDDING.
