Do you have a guilty pleasure, book-wise? Mine is true crime. I'm a sucker for Ann Rule and the like. I'm currently reading "Erased: Missing Women, Murdered Wives" by Marilee Strong. Yeah, it's about as tacky as it sounds (actually, she spent quite a few years studying cases like Scott Peterson, etc and formulates some interesting theories about 'eraser' killers, but still...)
I try to atone by listening to Charles Dickens' "Great Expectations" while I'm driving.
