It might not have been so hard to sell Jon West on the Deeps - if he hadn't had his heart set on the stars. Bitter disappointment over washing out of space school prompted his rash decision to join the Deepsmen who struggled to conquer Earth's last frontier and the threats it held for the North American continent. Based on the theory that man may someday inhabit the vast ocean floors, this tale is a speculative journey into that fantastic realm. Scenes in fabulous undersea cities, tense battles between men and colossal sea monsters, a running feud between Jon and a belligerent civilian youth - all combine to make this an exciting drama in the best science fiction tradition. Not until rumors begin about the Mindanao Trench and the mysterious Project called "X" - a project to save a continent -does Jon snap out of his reluctant attitude toward the Deeps and realize the full magnitude of a mission more dangerous than any on Earth or in space. Tidal waves, the descent to perpetual blackness seven miles under the sea, disasters that struck with lightning speed breed action that drives Jon and his fellow Deepsmen toward a powerful climax. Bryce Walton has written in Sons of the Ocean Deeps a chilling tale of the terrors and mysteries of the seas that will make readers long to live to see the day when man may invade Earth's most beautiful and most dangerous realm - the indomitable sea.
