Under the African sun, the shadow of the past is never far away. During the Rwandan genocide, three foreigners - UN worker Carmel Shang, military doctor Richard Dunlop, and journalist Liesl Nel - were forced to stand by, powerless to prevent the massacre and unable to escape witnessing the horrors. 20 years later, scattered across the world, the wounds of Rwanda still run deep. Now, a tattered photograph that was clutched in the hand of a dying man holds a clue that brings them back together... and hides a secret that is making them a target of an assassin. Hunted through South Africa's Kruger National Park to Zambia, Australia, and back to Rwanda, the three must bring themselves to confront not just the scars of a nation and a continent, but of their own hearts.
