Kildar by John Ringo

Kildar is a military fiction thriller novel by the author John Ringo. It is a sequel to his earlier book Ghost - the first in the Paladin of Shadows series - about the adventures of Ex-US Navy SEAL Mike Harmon (A.K.A. Mike Jenkins, Ghost, and 'Ass-Boy 1') as he engages in combat with various terrorist groups. In Kildar, he is lying low after his actions in France, wandering the less populated areas of the Caucasus.

Having angered every terrorist on Earth and at least five governments, former SEAL Mike Harmon buys a farm in a third world country. With terrorists knocking on the door and tenant farmers with a truly Byzantine culture, the question is whether he can drag the keldara into the 21st century before the Chechen put them back in the sixth.
