Right now I’m halfway through Michael Chabon’s Pulitzer Prize-winning novel “The Amazing Adventures of Kavalier & Clay,” which is the first fiction I’ve read in about a year. A friend gave it to me as a gift two years ago, but I only picked it up recently. It’s a good read and ambitious in scope, if a little over-rated. What makes it so entertaining is the very grown-up eye it turns to the comic book world, a kind of validation of the wide-eyed passion of geeky, power-starved, adolescent boys everywhere.
