But he never expected what would happen next. He finds himself hip-deep in international intrigue. Who is after him? The Russian GRU, the FSB, maybe even someone closer to home. Will he be able to save his family, his friends, and himself? Or will the villains defeat him in the end? And he joins the fallen at Arlington.
