Well what kind of stuff do you like? I love Martin Amis, as you can tell by my name; in particular I would recommend Money, London Fields, and The Information by him. I have also fallen in love with Haruki Murakami's work; everything I have read by him has been fantastic.
One of my favourite books of all time is Red Earth and Pouring Rain by Vikram Chandra, just a wonderful journey.
Currently I am working my way through In Search of Lost Time by Proust, brilliant so far.
Of course I mainly read fiction, so if you want non-fiction you should porobably ask someone else.
