J. F. Rivkin is the joint pseudonym of two unidentified women authors. They wrote separately and together, and have even appeared in person as "J. F. Rivkin (A)" and "J. F. Rivkin (B)". 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 with the female Wizard who hired her.
