A BLOOD DEBT MUST BE PAID WITH BLOOD. This is the message pinned to Will Kane’s door with a Bowie knife. And it doesn’t take long before the first of the Hard Flint Brothers arrives to make good on the threat. Kane barely escapes with his life, but things go downhill from there, with five more Brothers having sworn to take his life in vengeance for his killing of one of their own. ... Lurking behind it all, Kane is beginning to feel the presence of something bigger, an organization more secret than the CIA or FBI. One that has ties stretching back to World War II and involves the highest levels of power and seems particularly interested in him.
