D.T. Max's biography of David Foster Wallace, Every Love Story Is A Ghost Story: A Life of David Foster Wallace, comes out next week.
DFW is widely considered the most influential writer of his generation (I can't look at a footnote on Daring Fireball or Grantland without thinking of Infinite Jest), and he was certainly the most important one in my life. He was more than a guy who could spin mean prose; he was a model of intellectual clarity, ambition, and honesty. I'm in the midst of rereading his complete works for the third time now, and needless to say, this biography will go into that pile.
