In honor of the 100th anniversary of the very first Tom Swift novels, the first 4 were rewritten to make them more accessible--and more appropriate--for today's readers. Racial slurs were replaced although the speech cadence of the only Black character was retained. Additional mechanical and science information was added and sentence structure was modernized and tightened.
In this 4th novel, Tom Swift and his father complete an incredible undersea craft for a submarine competition they intend to enter. Most of the other entries want to do things the honorable way, but their main competition has other ideas.
Sabotage and attempted murder are not off the table as far as their new enemy is concerned. And, when an incredible fortune in sunken gold is now possible, the enmity between them increases to the point where only one may come back to the surface and live!
This novel includes details of the fascinating new form of silent propulsion Barton Swift devises and how his son helps make it a reality.
