A country fighting to stay free. A woman with an impossible decision. In November of 1939, Sini Toivola is sure of two things: she loves Marko Linna, and she has a comfortable life in Helsinki. But when the massive Soviet army invades her beloved homeland and Marko spurns her affections, her life is turned upside down. Needing a fresh start, Sini decides to join the female volunteer corps-the Lotta Svärd-and is sent to serve near the front lines. Service at a field hospital proves a good distraction-until Sini discovers a Russian soldier lost behind their camp. Duty requires her to turn him in, but her heart begs to keep him safe and help him escape. Torn between love for her country and love for her enemy, Sini must choose-but no matter what choice she makes, heart-wrenching consequences await them all.
