An ultra-secret State Department mission code-named Moonwinx propels Doc Savage from the concrete canyons of Manhattan to the icy black waters of the Arctic sea, and deep into the frozen heart of Cold War Russia in a daring Flight into Fear.
Targeted for assassination by the Kremlin and fated for a confrontation with a nemesis more violent and vicious than any he has faced before, the Man of Bronze must evade a faceless executioner known only as The Red Widow.
What is Project Moonwinx? Will Doc Savage survive to put this all-important plan into motion? Or will The Red Widow sink her poisonous fangs into his throat?
