Romance Bingo - Rogue square
Too much religious preaching and repetitive preaching at that. The religious preaching showed up in inopportune or inappropriate times (such as when Jack is having a major conversation with Heinrich Himmler and all he can think about is one-liners from the Bible - dude pay attention to your surroundings). There was one point in the preaching that crossed the line into bigotry; painting all pagans as evil because some Nazis believed in the occult and/or pagan spirituality was a big turn off for me.
Aside from the constant preaching, this was a good story about two British spies: Kat (a former Russian princess and now actress in Germany) and Jack (an American naval engineer on loan to the Brits). The conflict was something different than most of the romances I read - how do to spies trust each other with their lives, their hearts, and the missions? I thought the writing really captured how they went about trusting each other slowly while planning and completing the parts of the mission. There was an intensity to the espionage scenes that kept me engaged in the story. However, the author's note at the end (a substitute for an epilogue) felt sloppily written and as a last minute add-on to turn the HFN ending into a HEA. Personally, I would have preferred the HFN ending.
