Jennifer Pozner comes out swinging as she takes aim at the ''Reality TV'' industry and its ever-growing universe of so-called ''harmless'' shows in her book REALITY BITES BACK: The Troubling Truth About Guilty Pleasure TV, published by Seal Press. Pozner uncovers sexism, racism, classism, stereotyping, violence against women, phony psychological help and what really drives the content of TV we passively consume for entertainment. This is an important book, fun to read, and what Library Journal has determined ''an essential read.'' Pozner's research and analysis are mind-blowing, but you really have to hear Jennifer Pozner in person to understand the passion and knife-sharp wit she brings to her work.
