“Fibonacci’s Daughter” by M.D. Coverley (a pen name for Marjorie C. Luesebrink), published originally in New River in 2000, is a narrative and architectural puzzle. The main character, Annabelle Thompson, is the daughter of gamblers and a new-age opportunist. She sets up shop in California’s Huntington Beach Mall, where she uses numerology and Fibonacci numbers to peddle insurance policies to high school cheerleaders and football players — insurance against failure, that is. But probability is always chance, and the mystery that lurks here can be resolved in several ways. This piece is part of a larger collection, Fingerprints on Digital Glass, Web-native Fictions. Coverley is also the author of Califia from Eastgate Systems and the recently-released The Book of Going Forth by Day. See the Directory entry for more about this work and author.
