Imagine a distant future where the ability to travel through time becomes a central part of every country's national security program. Here's the premise behind this gripping science fiction novel by author Andre Norton. Time Traders is scaling up one such agent named Ross Murdoch, who has been tasked with taking a trip through history to ensure America has access to the latest space travel technology. The Scouts have uncovered something that defies faith, but the evidence is indisputable: The United States' worst enemy is sending its own agents back in time! And someone (or something) offers them technology and weapons far beyond our most advanced science. We have only one option: to create the time-transfer technology ourselves, to find a source of long-standing opposition. and remove it!
