All Tom Swift novels have more than the primary invention from the title, but there is a lack of details about those lesser inventions. How did they come about? Were they part of something else of standalone projects?This series of four collections attempts to put the story behind the 'thingamy' as in, "Tom raced from the room pausing only long enough to cream the thin gamy into his jacket pocket knowing it might come in handy later on."Now you have the latest tales of five of Tom's inventions, plus one from his father, Damon Swift. In this volume is everything from the fight to built a reconnaissance aircraft the Government needs instead of the one they ask for, an incredible set of new musical instruments Tom hopes will help a favorite teacher keep her music program, a high-dive from orbit in only a space suit, an engine that uses only sound, and a giant fish. Most of these are mentioned in various novels from the New Tom Swift Inventions Series (also available from this outlet).
