That Sweet Enemy. Marjorie May, #2

A scarred hero. A courageous heroine! Homebound after the journey of a lifetime, the resumption of the Napoleonic Wars traps Mary Burns and her companions in Switzerland. They find themselves suspected of espionage by the French and must persuade Captain Armand Dufour of their innocence.  Scarred, cold, and sarcastic, Captain Dufour makes no secret of his loathing of the English, but in his interrogations pays a particular interest to Mary.
Then he makes a scandalous proposal: he'll allow her friends to go free, so long as Mary remains with him as his wife! With no choice, Mary resigns herself to her fate. But amongst strangers and far from home, she finds herself drawn to darkly compelling and mysterious Armand. Why does he want revenge against Englishwomen? And can the touches of compassion and wit Mary sees in her husband persuade her to stay when she has the chance of escape? A sweet Traditional Regency Romance with the danger of war, a complicated military hero, and a heroine who will bring him hope.
