The signed hardcover should be along shortly.
You can now preorder the Metanatural Adventures of Dr. Black. It is a 366 page hardcover with an introduction by Jeff VanderMeer.
There is a signed hardcover with a dustjacket, which is limited to 100 copies, and a regular hardcover with a dustjacket. The signed version has special endpapers also.
I quote from the review:
“In my honest opinion it’s one of the best collections of the year.”
