There is an abandoned nuclear silo in the jungles of Africa. Sam Mackie isn't sure what it has to do with him, with his life. He's a mid-level pharmaceutical executive. He's divorced. He's lonely. But then someone kidnaps his son, Daniel. Daniel, the quiet kid who other boys picked on in school. Daniel, who understood how much his father had to work, and ate pizza alone for dinner most nights. Daniel, the only good part of Sam's life. Sam will do anything to get him back, including traveling halfway around the world to discover the link between his son, the dark nuclear silo, and his own mysterious past.
