It is the middle of World War II. America is now in the war on the Allied side; however, the Axis remains strong, and the tide of the war could turn either way. A deep undercover Allied agent working within the German military command structure itself makes what might be one of the biggest discoveries of the war, but her cover is blown, and she is captured before she can get the full details to the Allies. What she has been able to share, as well as information gleaned from other sources, is terrifying. The Nazis have taken their occult science and made it reality under the aegis of Projekt Regenschirm. They can raise the dead to fight for the Nazi cause. They are also creating new supersoldiers, ubermensch, that may very well be unstoppable on the battlefield. One man has been tasked with the impossible job of leading a commando team to penetrate the Nazi's most secure stronghold and render Regenschirm vulnerable to Allied destruction. He has ample motivation for doing so. His sister is the agent who first exposed Regenschirm and is now being subjected to the tender mercies of the SS in her captivity. His former girlfriend, who is another deep undercover Allied agent helping his sister with her work, has also gone missing with his sister's very last data drop on Regenschirm, and no one, not even the Nazis, knows where she is. Thus, Major Jonathan "Jack" Bradshaw has two very personal reasons for taking down Regenschirm for the Allied cause. Can he and his team succeed in their mission, or will the Nazis complete their evil plans and win the war thanks to Regenschirm's horrible progeny?
