Nguyen Pran Linh, the man who loves her, must deal with his own conflicted loyalties, both of heart and homeland. As they race through the streets, they play out a drama of love and betrayal that began twelve years before with their mentor, the larger-than-life war correspondent, Sam Darrow, who was once Helen's infuriating love and fiercest competitor, as he was Linh's secret protector and truest friend. As the sun sets on their life in Saigon, Helen and Linh struggle against both their inner demons and the ghosts of the past, in this sweeping epic that illuminates the wrenching horrors of war, the dangerous narcotic of obsession, and the redemptive power of love.
