Growing up on a poor farm in Missouri and learning how to sing opera from her war-scarred father, young Christina Cross has no idea the powerful forces of good and evil, of music and war, will one day pull her into the maelstrom of the Second World War, compelling her to make life-or-death-decisions about who she is fighting for and the price she is willing to pay.Like a masterful opera, Christina's War deftly transports the reader to early 1940s Paris where Christina and her sister, Nicollet, are sent by their father to live a better life with their Grandfather, Philippe Pétain. Philippe, eager to please the Nazi regime, envisions Christina's exquisite voice as a means to entertain Hitler and his officers. Yet, unbeknownst to him, Christina's heart belongs not just to music but to Laurent Gauvion Saint-Cyr, the charismatic leader of the French Underground who had recruited her into the resistance.When she defiantly refuses to sing, setting Hitler's fury aflame, Nicollet becomes a pawn in a dangerous game of power and retribution. Now, Laurent must not only fight for their country's freedom but race against time to save the two sisters from the clutches of a malevolent Nazi officer who revels in torture.
