In the near-possible world of Caliphate, Europe is an Islamic stronghold and the staging ground for the Final Jihad against the Great Satan - America!
Tom Kratman, in 1974 at age seventeen, became a political refugee and defector from the PRM (People's Republic of Massachusetts) by virtue of joining the Regular Army. He stayed a Regular Army infantryman most of his adult life, returning to Massachusetts as an unofficial dissident while attending Boston College after his first hitch. He has practiced law in southwest Virginia. In addition to Caliphate, Baen has published his novels, A State of Disobedience, A Desert Called Peace and its sequel Carnifex, and three collaborations with John Ringo in the Posleen War series, Watch on the Rhine, Yellow Eyes and The Tuloriad.
