Refugee from armageddon
Sam Yates' Job – Commisioner of Security for United Nations lunar headquarters – was a pretty boring one... until mankind's first extraterrestrial visitor arrived on the moon asking for political asylum.
Now, everyone wants a piece of the action; scientists, soldiers, and spies from both the U.S. and U.S.S.R. are determined to study the alien. But the petty conflicts of humanity are the least of Yates' worries...
Hunters are coming. Warlike, inhuman, light-years beyond us in science
and technology, they will destroy anything that comes between them and
the alien prey. Including Earth itself...
