– Thomas Wharton
It's been a while since I've read it, but from what I remember, it is a semi-modern fantasy novel that attempts to build a magical world based around the literary necessities of libraries and moveable-type printing presses. It was definitely unique compared to the more common fare of space-faring science fiction or the idealized middle ages of other fantasy books, though I suspect that means it won't find much of a fanbase among the usual audience for fantasy novels.
As I understand it, Wharton later continued to build upon the themes started in this book with a follow-up called The Logogryph: A Bibliography of Imaginary Books. Sadly, I've had no luck in tracking that other book down.
