The last book I read was The Talented Mr Ripley. Patricia Highsmith has written some very good books.
I don't have a favourite author, I read books almost at random regardless of who wrote them. Maybe if a book was utterly terrible I would avoid that author.
John Irving, Kate Morton, John Boyne, David Nicholls, Barbara Trapido, Joanne Harris - far too many to mention or even remember without going home & looking.
Bill Bryson, Tom Sharpe, Ian Rankin, Stuart MacBride and Peter James. I'm currently re-reading all their books again....for the millionth time!!. Love them all.
I like Milan Kundera for a bit of depth but my fave has to be Dave Eggers, I love his style.
Last book I read was Derren Brown's latest one, Confessions of a conjuror.
