Aurelia is a novel by R. A. Lafferty published in 1982.
Aurelia is a novel in which Aurelia is a 14-year old who goes to another world.
Dave Langford reviewed Aurelia for White Dwarf #41, and stated that "this is Lafferty, pushing 70 but still a bizarre and original author who's an acquired taste, and the book bulges with jokes and philosophy (hard to spot which is which), tall tales and weird people; horned men, sinister yo-yos, doppelgangers, the extra prime number between 5 and 7, and a worm with a gun. Indescribable. I loved it."[1]
