Boy Shielder is an action-packed science fiction book about the Bwanites: an intelligent and highly civilized race of people living on a distant planet called Terro who were driven off their planet after a fierce battle by a rival group called the Mallites. They discovered Earth, and after studying Earth's civilized nations, they decided to look elsewhere.
A twist in the plot occurred when Freddy, the adventurous son of Clenti, the Bwanite leader, took his two younger brothers, Tony and Sammy, on a shuttle trip to Earth. They intended to land in the United States of America. However, with Freddy's inexperience, combined with some malfunctions on the shuttle, they crash-landed in Russia.
This begins a series of adventures as they try to get to the United States of America.
