Great writer, but I gotta say; the only writer for me in the "Roth section" is Joseph Roth, and they have so similiar names, so people often mix them up. Sad that Philip Roth didn't recieve the nobel before passing away.
The plot against America is a fantastic novel, with some sinister echoes of the current political climate in the States. Check it out if you get chance! RIP Mr Roth.
