The Lost Rose of Winter by Robert Valleau

Two souls, united for a brief moment in war-torn western Europe during World War II, is more than a coincidence. Major Daniel Humphrey, a former high school teacher, is injured while on a reconnaissance mission for General Patton’s Third Army at the start of winter in 1944. He is transported to a hospital in Nancy, France, where he meets a pretty American nurse named Cassandra Burns. For him, it is love at first sight, but it is only temporary. The next day she disappears, and he is told she never existed. However, the rose she left on his pillow tells him otherwise. After the war ends the following spring, Daniel confirms Cassie’s existence but she did not return to the states. Fearing she died or is missing, he visits the place where they first met and unknowingly opens a Pandora box of intrigue that changes his life forever. Cassie is an American spy and married to one of Hitler’s most notorious spymasters for the Eastern Front — Oberfuhrer Erik Bauer. Now, armed with information about Bauer’s plans to destroy the West’s restructuring efforts, Cassie is on the run. Cassie wants out of the espionage game, but what price will she pay for leaving? Can Daniel find Cassie before Bauer and his band of Hitler loyalists find her first? Is Bauer the only threat to Cassie's safety, or is someone more sinister hiding in the shadows?
