Tom Swift has developed an ultra-powerful telescopic device that promises to yield dramatic new insight into the deepest mysteries of the universe. But, his first discovery is no more than 200 miles up, and it's a shocker. A tiny cube of polished granite is orbiting the earth, and on its side Tom spots a message - in a language no one has ever encountered before!

Tom Swift has developed a powerful new kind of nanotechnology - incredible shrinking robots reduced to the size of a pinpoint with his revolutionary molecular compressor. But, the tiniest miscalculation can have gigantic consequences, as Tom soon finds out for himself. One moment he's running an experiment - and the next he's running for his life!

Tom's newest invention is stolen, along with Sandra Swift's new device, a special suit that helps firefighters battle fire safely. Now a man who calls himself Captain Invisible starts playing superhero. But there's a fatal flaw in the suit--and if it isn't recovered in time, Captain Invisible may become Captain Toast.

Propelled into a fantasy world through his Total Reality Generator--a computer game that electronically recreates true-to-life scenarios--Tom discovers that the game has turned frighteningly authentic and that he could be in genuine danger.

Something fishy is going on down at Laguna Pequena Beach. The ocean has turned into an aquatic nightmare. A grotesque giant squid, a hideous herring with razor sharp teeth, and a gruesome fifty-foot shark have laid siege to the shore - and many lay the blame on Tom Swift's latest oceanic research!

Tom's work on a psychotronic translator, which deciphers brain waves and reads minds, has been interrupted by a small earthquake. But the minor tremor may have major consequences: a terrorist group using stolen nuclear material has vowed to turned the epicenter of the next - and much more massive - quake into ground zero!
