Novel (1992) by Robert Rodi concerning Natalie Stathis, the fag hag of the title, who falls in love with her gay friend Peter Leland. They go out clubbing a lot; every time he meets a man she tries to split them up, surreptitiously. Peter, however, falls in love with Lloyd Hood a 'survivalist' and not Peter's usual type at all. Natalie can't split them up. So instead she kidnaps Peter.
It's great fun, massively readable, hugely funny, and occasionally sidesplitting. Natalie has a large Alsatian guard dog called Brynocki. When she discovers that the dog is afraid of thunder, and unable to help her with an intruder (Lloyd, as it turns out), she yells at the dog: 'I'm going to feed you cat food till the day you die'. Marvellous stuff. Highly recommended.
