" Arguably, Heinlein's most racist novel. Haven't read it since I was a teen, and I remember Heinlein's characterizations of the "Pan-Asiatics" as awful even then, and yet it was a solid, entertaining SF story. Since it's been almost thirty years, thought I'd see how it stood up. And you know what? It's still a gripping story with an excellent premise. The racism isn't quite as bad as Mickey Rooney's portrayal of Mr. Yunioshi in Breakfast At Tiffany's, and I can overlook the absence of any female characters (except for the briefly mentioned secretaries) by just remembering that it was written in 1941. It's not Heinlein's best by any measure, but neither is it an embarrassing mess, as I Will Fear No Evil. "
