Frenchgirl, I used to love Paul Auster for the first few books but after a while I found him rather depressing as all his books are about people screwing their lives up!
Keep thinking of new ones
The Reader by Bernard Schlink is one of the best books I've read, as is Perfume by Patrick Suskind (if a little odd, but truly an amazing book)
J M Coetzee is brilliant as well, esp Disgrace, The Life & Times of Michael K, in fact any of his.
Rupert Thompson is good, (Dreams of Leaving, The Five Gates of Hell, Air and Fire. The Insult is the best I think. Didn't like Soft so much but the Book of Revelation was better)
So is Joseph O'Connor, who I believe is Sinead's brother. The Salesman & Desperados are my favorites.
Sorry to keep listing books! Amazon usually has pretty good reviews.
