"If you've read Heinlein before and liked what you saw, Friday is a fun tale following the path of a genetically engineered courier / secret agent. It's an entertaining read, just the thing for taking a step away from the here and now for a while.If you're unfamiliar with Heinlein, a warning might be in order. Heinlein has been called a misogynist or a lech by some, and this novel is an example of his work that might prompt such an assessment. At several points the story voices the author's attitudes about sex and gender relations. (A blurb on the back from the New York Times Book Review reads: "... she can think better, fight better and make love better than any of the normal people around her.") A quote from one of the principal characters sums up what seems to be Heinlein's view: "Geniuses and supergeniuses always make their own rules on sex as on everything else; they do not accept the monkey customs of their lessers." To be sure, this element does not dominate the story, but some might find it to be a turn off. I prefer to believe that Heinlein simply refused to constrain his imagination to technological visions of the future."
