A COLLECTOR OF AMBROSES AND OTHER RARE ITEMS features four tales of SF and fantasy, including the title story, in which three unscrupulous book collectors encounter a true “Completist”; “The Boy in the Iron Mask,” which touches on the contamination of reality by dreams; “The Slaves of Moxon and Other Tales of Scientific Romance,” in which the SF world has to deal with an alternate history version of…itself!; and “A Reply to L. Ron Hubbard.” Great stories by a master storyteller.
