Peter Straub explains:
“What Subterranean Press will be publishing is an earlier state of the novel now called A Dark Matter, not merely the limited version of the trade edition. I wish to have it preserved and published in this form as well as the final, many-times-re-edited form to indicate what I hoped its shape would be like. This is a much looser, sloppier, more wild-eyed version of the book, with blind alleys, red herrings, and false trails."
Straub's also edited two anthologies ready for release this fall, the 1,500-page "American Fantastic Tales": Terror and the Uncanny from Poe to the Pulps and Terror and the Uncanny from the 1940s to the Present.
