SFX, Gollancz and Waterstones have teamed up to run a promotion on HOUSE OF SUNS. If you buy the current number of that fine periodical (SFX 198, it says on the website) you'll find a coupon that you can take to certain participating branches of Waterstones, and thereby claim a free paperback copy of HOS. That's right - free. Nowt. But there are only 4000 copies, so if you want one, best not hang around.
SFX also ran a brief interview with me in connection with this - read it here.
