Andre Norton and Sherwood Smith have collaborated on Solar Queen and
Time Traders novels, but never before have they created as rousing an
adventure as awaits Ross Murdock, Gordon Ashe, and the rest of the Time
Patrol in ancient Atlantis. In Earth's future, when time travel has
become possible, the Time Patrol is the top secret government agency
that protects Earth's past, so that our history will not become
corrupted by invaders from either our future or from other worlds. For
many years, Murdock, Ashe, and other members of the Time Patrol have
contended with threats to our time continuum, none more deadly than the
alien Baldies, who hate other high-tech civilizations and want to
destroy Earth. Evidence of time travel has been found in ruins dating to
the ancient world...in the legendary realm of Atlantis. So Murdock,
Ashe, Eveleen Riordan, and other Time Patrollers deck themselves out as
foreign traders to discover whether something is amiss in Atlantis. They
find that the Baldies are there, as evidenced by sophisticated,
high-tech equipment, whose purpose it is impossible to fathom. As they
try to derail the Baldies' plot, the Time Patrollers realize that time
is running out on their mission, when Atlantis is shaken by tremors that
presage a cataclysm that may be the disaster that sank the fabulous
island state. But they must be sure they act to preserve, not destroy,
history--and if they're wrong, it'll be too late...for them and for
Earth's future.
