The Zimmer Doctrine, Paperback

While The Zimmer Doctrine stands as a beacon of courage and hope, its architect, American President Brandon Zimmer, still needs his most important ally at his side. But rocked with personal loss, and a nagging sense of doubt and inevitability, Cal Stokes may no longer be the man to stand with his friend, or to lead the warriors of The Jefferson Group. What does the future hold for this once stalwart patriot, and what might his inaction mean for America and its allies?
