Dangerous rivals for treasure trying to foil Tom's plans lead to underwater battles! Join Tom and crew as they use advanced - yet untested - designs to defeat crooked adversaries for both treasure and the secrets of Tom's sub. Fantastic underwater combat finishes the book! Tom Swift, the inspirational boyhood hero of Steve Wozniak and Isaac Asimov, is an all-American young inventor in his teens. These fantastic and future-predicting stories are VERY alive today. Swift was modeled after the entrepreneurial and inventive geniuses Henry Ford and Thomas Edison, who both changed our world more than any other two people. Like Arthur C. Clarke, Swift invented or predicted many modern discoveries including the Taser, camcorder, video-phone, electric car, and several others.
