In this 8th in the new Tom Swift Invention Series, Tom Swift finds himself involved in a galactic mystery. Something very much like a black hole has been discovered a dozen light years away, but nobody can say for certain what it really is... or if it will affect the Earth. The thing about black holes is they suck in light so they can't really be seen. Tom wants to go investigate. Even his quickest unmanned rockets can't carry enough fuel for such a trip. So a shortcut seems to be the only chance. His knowledge tells him that wormholes are more than a science fiction hypothesis, but how the heck can he go about locating one? Even if he finds one, how can he determine where it might exit? When an old video surfaces showing proof to and open and willing mind that wormholes exist and can be opened for brief periods, he also finds it takes the power of a nuclear bomb to do so. If he overcomes all issues, he and Bud may be on a one way trip. They encounter the anomaly-and it's a doozy-but they also find themselves face-to- uhhh, hands? Giant ghostly hands beckon them, but what can it all mean? With little air and no fuel, what can Tom do? NOTE: Although this book shares a common title with one of the Tom Swift Jr. books published in late 1971, it IS NOT that book. Nor is it that story.
