The 2007 Pulitzer was awarded to The Road, by Cormac McCarthy, one of the best books I've ever read! It's Oprah's current pick, but don't let that deter you from reading it. It's post-apocalyptic fiction, stark--the language is spare for McCarthy. He writes the way Faulkner writes, usually, but, as the novel goes on, language begins to fall away and the conversations become more and more spare.
It's just a beautiful, awful, tragic, hopeful novel.
