Kratman was recruited as an author by ex-soldier and publisher Jim Baen who " recruited a batch of younger , like-minded authors from similar backgrounds " ; Kratman , Michael Z. Williamson , David Drake and John Ringo . Commonalities in the works of these authors include the setting of a civilization in decline with heroes battling against conventional wisdom . Kratman 's first novel , '' A State of Disobedience '' , deals with a revolution against tyranny in a future United States . The book was described by Lesley Farmer in '' Kliatt '' as a " libertarian-inspired combat story " with shallow characterization . Another politically-oriented stand-alone novel , '' Caliphate '' , takes place in a future Islamic Europe where a German girl is sold into prostitution to pay her family 's yizya . The work has been described as a part of a trend towards more speculative fiction focus on Islam after the September 11 attacks and as driving " some readers to apoplexy " . Mark Steyn discussed the novel 's political aspects at length and also described it as " a brisk page-turner full of startling twists and bad sex "
