Query: Nuclear Hijinks, Awesome Trains, and Metaphysics

At the beginning of this original novel, a nuclear physicist with a definitely bent view of reality climbs a shot tower, intending to use the atomic bomb as transportation into the universe next door. Not far away a hapless lieutenant named Perkins boards a bus bound for Camp Sagebrush and, so he believes, a rising career in the New Atomic Army. As the countdown to detonation to proceeds, a small civilian plane, piloted by a couple of strong-minded women, searches the darkness for clues to a mystery that will surprise and probably scare you to death. Reading The Atomic Express is like watching an action movie, but the subtext is totally surreal. If you appreciate off-beat humor, high intrigue, the metaphysics of quantum science -- and of course trains -- you'll love this book!
