A study by Emory University suggests that reading a good fiction book may boost brain function for days, even after finishing the book.  It seems that reading triggers a part of the brain that basically tricks it into thinking it’s doing something it’s not…in this case, actively participating in the story.  It’s not clear what a boost in this area of the brain actually accomplishes for you, but hey, it’s cool science nonetheless.  Read more about the study here.
