While attending the Henley Royal Regatta in England, Samantha Norquist, an American photojournalist, inadvertently overhears three men plotting to illicitly ship weapons to the Congo. Her photographs of Che Guevara had garnered her international recognition and now this secret information would alter her career in Europe and catapult her into a wild and dangerous assignment in Central Africa. The story follows gunrunners on the shark-infested Zambezi River and across the Rhodesian savanna with its profusion of animals and birds. Focus is a tale of love, joy, greed and malice. It transports the reader through the turbulent years of 1960-1961 in Europe and Africa and ends with an event that stuns the world.
