A Light in the Darkness by Regina Santos

On a beautiful autumn day, in a small Swiss Café, a French nurse and a German engineer fall in love with one another right before WWII. Francine captivates Hans with the intelligent way she expresses her thoughts and with her independent nature. And Hans couldn't be more perfect for her with his attentive, caring and assertive personality. But just like the turning autumn leaves, everything changes with the outbreak of the war—and the distance between them grew into immeasurable proportions. However, fate finds a way to reunite them again, in the most unexpected place. Their journey through love, pain, suffering and adventure would change them forever, as they relentlessly try to hold on to hope, and as they survive and search for a way out, for a light in the darkness.
