The Library of the Universes (and other Tales of the King Imminent)

These are the tales that underpin the Walkerverse and all the novels that are set within. These are the tales of the books once scattered from the Library of the Universe and now being found, being hunted.
For they contain stories of old, but also knowledge, great and terrible knowledge and the truths of the dreaded King Imminent.
Not only do these stories stand alone, but they also form the basis of the meta-narrative that ties all of the author's books together.
