The name alone is a dead giveaway that this book is not to be taken seriously. Judging by that standard, it succeeds in its mission to entertain for a couple of hours reasonably well, though 30 year old alternate history books face a curious dilemma: the atomic train in the book is really old-fashioned and slow by today's standards, but I'm not sure if it was meant to be that when the book was written or if it was meant to be a shining example of progress in that alternate universe.
