anything by Iain (M) Banks
particularly Espedair Street, The Crow Road or Complicity.

I, Lucifer by Glenn Duncan is good.

if you like sci-fi, try Pandora's Star by Peter F Hamilton, or Iain M Banks sci-fi stuff.

The Three Musketeers is a good read too.

As well as Ian M Banks,
I would like to recommend Ken MacLeod, Alistair Reynolds and Charles Stross for sci-fi purposes.

For oddness, China Mieville.

For spectacular words-per-pound value and brilliant writing, Neal Stephenson.

Banks
Seconded. Try 'the Steep Approach to Garbadale' - a fabulous read.

or 'Excession' - a non-stop thrill-fest of a book.
