Within each Tom Swift novel there are a couple major characters who you get to know, and a lot of secondary characters who walk in, say a few lines, and walk out. You never get the chance to know who they are other that in that context I have set about writing back stories for these people. The novels may not have the 9,000 - 15,000 words to devote to giving you a good background story about them, but these collections do. This third book contains stories about the two men at Enterprises who are always getting mistaken for each other (and how they finally fixed that ), the journals of Doc Simpson and his many times spent fixing Tom after he has been injured, how Tom met his girlfriend while building his giant aircraft, the Sky Queen, the story of the Swift's super-efficient secretary, Miss Trent, and the tale of Tom and Bud entering a man-powered kinetic sculpture race.
