David Fisher is an EPA agent, Environmental Perfection Agency. This is the first clue that "we ain't in
Kansas anymore". Turtledove is the master of alternative
history. This particular tale is heavily
laden with Turtledove tongue in cheek humor while maintaining a consistent and
intriguing plot. GM isn't General
Motors it is General Movers, manufacturer of flying carpets. The theme is a realty fueled by religion and
magic being threaten by "Powers"
that may be trying to start the Third Sorcerous War.
Turtle writes a great story and twists his plots to sufficiently satisfy any plot driven reader. Fisher is a civil servant with a conscience and is driven to perfection by both his ethics and his love for Judy, a proof reader in a scriptorium.
There is plenty of action, lots of really, really interesting and funny characters or scenes.
I highly recommend.
This book may have been received free of charge from a publisher or a publicist. That will NEVER have a bearing on my recommendations.
