From Library Journal:
In 1908, did the mad genius Nikola Tesla, who beat out Edison in the Battle of the Currents (which should it be, AC or DC?), invent but then hide a death ray, a weapon that could blow a fleet of enemy bombers out of the sky in one instant? By 1943, it looks like the Germans have some very nasty tricks up their sleeves. So writer Robert Heinlein, in charge of the “Kamikaze Group,” a think tank composed mainly of his fellow science fiction writers—Isaac Asimov, L. Sprague de Camp, and L. Ron Hubbard are among them—sets out to find the truth. If a death ray exists, they’re determined to locate it and make it work—for America’s side!
Time and again, you’ll think there couldn’t possibly be any more new plot twists in this madcap adventure by the author of The Chinatown Death Cloud Peril and Jack London in Paradise, but five pages later a new one will hit you on the head. VERDICT Anyone who loves the science fiction of the 1930s and 1940s will want to read this delightful romp. It’s so much fun that it virtually defines what light fiction should be.
