This is a well written story, with seriously deviant non consensual acts of pain and sex on the two main female protagonists as well as all its females in supporting roles! There's a duel story here, one set in England and the other in Germany, in the final year of world war two. It has a detailed espionage story gaining information from the enemy in order that it may shorten the war running throughout. There is considerable detail, and events linked to factual events that make it plausible in many ways. The German events. Young nubile women deemed Aryan were used for breeding and for sexual favors during Hitlers Third Reich. It was classed as honorable and essential to the war effort. So the SS/SD/Gestapo security/political forces having a brothel or free sexual use of Aryan German women happened. That these men were some of the most sadistic to walk the planet has also been evidenced as fact. Therefore, the components of this story where Lisl and other young women are compelled into being the masochistic or non masochistic but tortured sex slaves of sadistic officers is not so far fetched, but horribly plausible. Then the story of the British army officer, often portrayed as heroic in the propaganda we get fed was quite a shock to see the Major and subsequently the Colonel and Private as sadistic, self serving, uncaring bastards too. In fact they were worse in many ways as they blackmailed, used and abused their female victims in such a manipulative and uncaring fashion. Pam and Lisl are apparently of opposite sides, but of the same ilk submissively, by their grooming over a period of time for their Masters to see how far they can go in their ever stretching limits of sadistic torture and pleasure. I guessed the rescued captive, kept captive, Kay would turn out as did. I'm pleased to see Lindsey Brooks the writer give suitable empowerment and come uppance to each of his characters good and bad throughout the story. The tantalizing end with the Colonel and papers did surprise me, yet self serving and self preservation is a definite human trait that this author has exploited in his characters extremely well, in all of them! The story has been edited and standard of English is good. The historical knowledge is sound, including people trained as overseas operatives in espionage. The characters...well you'll love them and I guess hate some, both the major and minor characters (scuse the major pun) this is not an easy or light read, it is dark, cruel and definitely non con. I thought about this in terms of 4 and 5 stars and grudgingly give 5 stars. Why grudgingly, well if you can read this content without qualms you do better than I. Part of this horrified me but like a snake mesmerizing its pray, I was hooked to the end. What is says of me I dread to analyze but I have to recommend it if tough enough, hence the 5 stars.
