For a nearly 80-year-old fantasy novel, the book begins with a remarkably modern sentence:
Multiverses are all the rage in cosmology today but parallel worlds were a seldom-used concept either in science fiction or fantasy in 1940 when Fletcher Pratt came up with the multiple possibilities for humor and adventure inherent in sending protagonists into the world of story and myth.
He teamed with L. Sprague de Camp, then just breaking into regular sales, for a series of stories they sold to John W. Campbell’s Unknown Fantasy Fiction. “The Roaring Trumpet” (May 1940) and “The Magic of Mathematics” (August 1940) were incorporated into The Incomplete Enchanter, published in 1941 by the prestigious mainstream publisher Henry Holt. Prime Press, a rival small science fiction press to Gnome, reprinted it in early 1950, a year after they published de Camp’s similarly-themed Lest Darkness Fall.

At just about the same time in 1950, Gnome published de Camp and Pratt’s The Castle of Iron, an expansion of an Unknown novella from April 1941, presumably for no better reason than confusing bibliographers. That’s because this title is the sequel to The Incomplete Enchanter and not Gnome’s earlier de Camp and Pratt book, The Carnelian Cube.
In other words, Prime printed a book that looked like a sequel to an earlier book of theirs but wasn’t and Gnome printed a book that was a sequel but not to their earlier book – with both of them hitting bookstores at the same time.
I can understand why both of them did it. Publishing books randomly because you can get the rights, though, is not a long-term business plan.
Castle does have perhaps the oddest second binding tell of any of the mysterious Gnome variants. Even CURREY missed it in his first edition, although it appears in his 2002 Revision. The first binding has “Gnome Press” on one line on the spine; the second has “Gnome” and “Press” on separate lines. Imagine how easy identification would be if the number of lines always corresponded with binding state! Unfortunately, their priority is not known. My guess is that because the two-line version is so rare that it is the second binding but that cannot be proven.
August Derleth reviewed this book in the September 27, 1950 Madison Capital Times:
[It] is a far better brand of fantasy entertainment [than Minions of the Moon].

Damon Knight, Worlds Beyond, December 1950.
There is magic in the teamwork of de Camp and Pratt that is approached by no other collaboration in the short history of science-fantasy: that rare, happy spark that fuses two talents into a third more richly productive than either alone.
Basil Davenport, New York Times Book Review, August 13, 1950.
The result is pure extravaganza and pure delight.
