'The Things They Carried' is fantastic. I had to read it for school back in eleventh grade, but I loved Tim O'Brien's use of language. I've not read fiction in quite a while, though; I've focused on nonfiction for the past year, primarily books on rock music or mathematics. Which is so far a good idea, as I've since read stuff I wouldn't have touched back when I read fiction.
Currently going through Douglas Hofstadtler's (weighty) Godel, Escher, Bach. The idea so far seems to be about the need for mathematical formalism in proof-writing, but I'm expecting the author to take the floor from under my feet and reveal that the book is about something completely different at any second.
