Hearts Under Fire by Kathryn Kelly

North and South. Enemies and Lovers.

When a steamboat explosion gave a Southern cavalryman the opportunity to fake his own death, he followed his idealism and began fighting for the Yankees. However… he found himself on southern soil fighting against his own people. When he was shot by a man defending his home, the man’s granddaughter – the southern belle of his dreams, saved his life. How would he reconcile falling in love with a woman who was supposed to be his enemy? Had he made the wrong choice in fighting for the north?
