TOM SWIFT AND THE
VISITOR FROM PLANET X

By VICTOR APPLETON II

Tom Swift Jr. and his associates at Swift
Enterprises wait breathlessly for what
may well be the most important scientific
event in history--the arrival of the
visitor from Planet X--a visitor in the
form of energy. But there are factions at
work determined to snatch the energy,
which Tom has named Exman, from the
young scientist-inventor's grasp. First,
a series of unexplainable, devastating
earthquakes threaten to destroy a good
portion of the earth, and Tom suspects the
Brungarian rebels who obviously would like
to capture Exman and use the space visitor
to further their own evil purposes.

With the security of Enterprises and Exman
at stake, Tom creates two of his greatest
inventions--a Quakelizor to counteract the
simulated earth tremors, and a container
or "body" to house the energy from outer
space.

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.
