Virginia cavalryman Kieran Selkirk is summoned to a clandestine meeting in the winter of 1774. There he finds none other than Benjamin Franklin, who reveals the brilliant soldier's assignment: He is to travel to Russia disguised as a British mercenary and convince Catherine the Great not to join the British in their war with America. It is not a quest for the weak of heart, for to succeed, Selkirk must survive savage terrain, starving wolves, secret assassins, marauding Cossacks, a court of seductive young women, and even a dramatic romantic face-off with the legendary Tsarina herself.
