Two heroes fight across both earth and an alien world during World War II. P51 Mustang ace, Captain John Crickshank, while patrolling above the Congolese jungle, encounters a Nazi jet plane. The jet is armed with a device that thrusts him and his P51 into the alien world. Giselle Isubu-Petitclerc is the beautiful and deadly daughter of a French missionary father and an African mother. Educated at the Sorbonne, she is also an expert jungle fighter. Crickshank fights to survive in the alien world with the help of an assorted cast of similarly transported soldiers and pilots. At the same time, Giselle battles through forbidden areas of the Congo to discover the truth of Nazi designs on earth. Both Crickshank and Giselle battle to stop the Nazis, but other deadly foes, including two ancient demons - the Impundulu - are in the way. Inspired by Edgar Rice Burroughs and H. Rider Haggard, War Worlds is a high adventure where merciless Grey Warriors, the mythical and vampiric Impundulu, a psychopathic German corporal and an army of terrifying Stickmen stand between the two heroes and Nazi ambitions. War Worlds is written for adult audiences.
