Couple of fairly interesting articles at the Guardian site;
1) http://www.guardian.co.uk/books/booksblog/2010/jan/20/apocalypse-literature-now – Brief overview of current state of modern post-apocalyptic fiction. Some of the comments following the article are well informed and suggest further reading.
2) http://www.guardian.co.uk/books/2010/jan/09/james-ellroy-david-peace-conversation
– Yup, David Peace (Red Riding quadrilogy, The Damned United, GB84) meets James Ellroy (Black Dahlia, LA Confidential, American Tabloid).
