Tom Swift the Microbots — Victor Appleton

UNDER THE MICROSCOPE...AND UNDER THE GUN!
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!

Zapped by the molecular beam, Tom and his friends are thrust into a miniature but deadly world. A squadron of bees and an army of ants look to make short work -- and fast food -- out of the bite-size band. But their most dangerous enemy of all is the ticking clock. The condition may soon become irreversible, and time, like everything else, is shrinking fast!
