Martin Amis Time's Arrow
John Wyndham Kraken Wakes
Martin Millar Milk, Sulphate & Alby Starvation (not necessarily the genre you are after but I like his stuff fun & quirky, try it for a change/something lighter.)
For fantasy/sci-fi &c have a listen to BBC7 they put a lot of good stuff on there (classics & modern), & if something catches your ear you can look into the author further.
(Or.. rush into your library & grab the first thing you see; it'll probably be How to Care for your Tortoise, or Coping with the Menopause but ya never know, you could make a really great random find).
