Set in the 2070's, this story transports the reader billions of miles across the Solar System, from Earth, to Mars, to Jupiter and back again. With Augie Rodriguez, Boy Scout, Mars Colonist, mutineer, inventor, diplomat, chess player and math genius as your guide, you will learn the purpose of an alien structure discovered on Mars 25 years earlier, be present at the invention of a new propulsion system for spacecraft and observe a revolution as the colonies break free of their Earth-side masters. Augie is also instrumental in executing a plan to avert a third world war, a war that would have had disastrous consequences for the colonies on Luna, Mars and Callisto as well as for the people of Earth. A reluctant warrior, Augie emerges from a battle beneath the surface of the moon as a hero. Interwoven with interplanetary intrigue is the story of a young man who has to grow up fast when he finds himself confronted with problems that would challenge the most experienced adult. When Augie realizes that the girl he is sweet on is in love with his best friend, the strength of his character is tested; but with the help of his friends, he prevails and learns some things about himself in the process. While this book stands alone, it is set in the same past and future historical time track as The Man Who Conquered Mars and the soon to be released Titus Andronicus Scott. You will enjoy the action, intrigue, romance and a peppering of science that fill this exciting story.
