The Life and Loves of a She-Devil — Fay Weldon

This is not a book for everyone, but its admirers are vigorously enthusiastic. For example:
Rhoda Koenig in New York Magazine, who calls it ". . . a novel of blazingly hot revenge, one that amply illustrates the saying about heaven having no rage like love turned to hate, nor hell a fury like a woman scorned."
Or Rosalyn Drexler, who said on the front page of The New York Times Book Review, "It affords a scintillating, mindboggling, vicarious thrill for any reader who has ever fantasized dishing out retribution for one wrong or another."
Or Carol E. Rinzler, who wrote on The Washington Post Book World's front page, ". . . what makes this a powerfully funny and oddly powerful book is the energy of the language and of the intellect that conceived it, an energy that vibrates off the pages and that makes SHE-DEVIL as exceptional a book in the remembering as in the reading . . . . a small, mad masterpiece."
