Kindle. Brief and not very frightening as it reads like a fascist scarer of days long dead. Having one group of oppressed people being saved from their oppressors by another group oppressing the oppressors is lame. Conveniently the Führer-figure spontaneously combusts during the intervention. This is the first Saunders effort I've read, and I can see how he might appeal with some funny stuff in the small.
Eric Weinberger is dead right that this sounds like a work out of time.
