That’s David Foster Wallace’s unpublished novel, the one he was working on when he decided to exit this plane of existence, and which is due to be published in 2010 sometime.
As with the first part, The New Yorker magazine has published this second installment. Check it. You will not be sorry.
I know that I am something of DFW sycophant (if you’re going to be one it might as will be to a worthy host) but I’m very confident that this is going to prove to be an exceptional work, even in it’s incompleteness. In any case, I’ll be checking amazon.com (nothing yet) regularly for the exact release date.
