The Martian Emperor (A Chronological Man Adventure) by Andrew Mayne
Second in the series. The first was my pick back in early June. In this book, our hero and heroine pick up a number of months later. They travel to New York City by way of Smith’s private, and off the books, train, in order to face a new menance. The “Emperor of Mars” is blackmailing the Earth. They run into his old friend Theodore Roosevelt, and have a series of adventures. During the course of said adventures, we learn some more about Smith and his background. A ripping good yarn and well worth the $0.99.
