While perusing scans of old pulps, an ad in a 1951 issue of Imagination really grabbed my attention. “The Most Exciting Book Since Merritt’s Moon Pool”, the ad declared. “An original, never-before-published science-fantasy novel of the calibre of the great classics of Merritt, Taine, Wells… told with the gripping realism and brilliance of another Poe!” Well, damn, who wouldn’t want to read that?
