War World: Falkenberg’s Regiment is the first new John Christian Falkenberg novel in over 20 years. Falkenberg was created by Jerry E. Pournelle and made his first appearance in “Peace With Honor” in Analog Science Fiction and Fact in 1972. That and other Falkenberg stories appeared in his fix-up novel, The Mercenary. Colonel Falkenberg and his 42nd Marine Regiment served as the last line of defense of the CoDominium and its many colonial words. This book continues the Falkenberg story, detailing his adventures and those of the 42nd CoDominium Marines on Haven (War World) and on Churchill, as Falkenberg and Admiral Lermontov struggle to keep the CoDominium from fracturing. On Haven the Colonel finds himself set between the Mahdi and his fanatical forces, on one hand, and Dover Minerals and the Bronson family, on the other hand. While on Churchill, Falkenberg is called upon to rectify the problems caused by the CoDominium Bureau of Relocations wholesale dumping of antagonistic populations on the hardscrabble world of Churchill, previously settled by British subjects in favor of the monarchy. Nor, does it help when the Brotherhood, a conspiracy of colonial CD military officers, gets involved providing weapons and money to the rebels.
