A permanent manned space station 22,300 miles above the earth is Tom Swift's latest project! The daring scientific venture becomes a necessity when Tom discovers that his remarkable new solar battery can only be produced outside Earth's atmosphere. A factory in outer space is the bold solution - if the young inventor can find a way to launch supply rockets at an unprecedented rate, and can overcome a fiendish enemy and the mysterious gorilla-like phantom stalking Tom and his friends.And this is only a prelude to the dramatic events that unfold on the Pacific island of Loonaui where the Swift Enterprises space effort is being readied. From the terrifying moment Tom falls miles through the stratosphere to a final fiery plunge to Earth in a runaway space outpost module, Tom's adventure offers a drumbeat of thrills and action.
