Joint pseudonym of two unidentified authors, one of whom was apparently born in 1951. Of greatest interest is their Silverglass sequence – Silverglass (1986), Web of Wind (1987), Witch of Rhostshyl (1989) and Mistress of Ambiguities (1991) – featuring a female mercenary in Sword-and-Sorcery adventures in a brightly drawn Fantasyland as she guards the female Wizard who has hired her. Other JFR works include Runesword: The Dreamstone * (1991), and Age of Dinosaurs #1: Tyrannosaurus Rex (1992), which is sf. [JC]
