Now on sale at Abebooks - I find this signed edition of my favourite novel, Dog Soldiers by Robert Stone. Too bad I ain't got the $550!
Stone has inscribed it with a passage from the novel (don't try to read his handwriting:)
"In the end if the serious man is still bound to illusion, he selects the worthiest illusion and takes a stand."
Well, if I wanted to own a valuable book, that'd be the one...
