If the earthquakes cannot be stopped,
the entire world will be threatened by
destruction, and the Brungarian forces
will conquer the earth. How Tom utilizes
all his scientific knowledge to produce
swift-action results and outwit the
Brungarians makes one of the most
exciting Tom Swift adventures to date.
