The Winter Ghosts - Kate Mosse

World War I robbed England and France of an entire generation of
friends, lovers and futures. In Freddie Watson's case, the battlefields
took his beloved brother and, at times, his peace of mind. In the
winter of 1928, still seeking some kind of resolution, Freddie is
travelling through the beautiful but forbidding French Pyrenees. During
a snowstorm, his car spins off the mountain road. Freezing and dazed,
he stumbles through the woods, emerging in a tiny village, where he
finds an inn to wait out the blizzard. There he meets Fabrissa, a
lovely young woman also mourning a lost generation. Over the course of
one night, Fabrissa and Freddie share their stories. By the time dawn
breaks, Freddie will have unearthed a tragic mystery that goes back
through the centuries, and discovered his own role in the life of this
old remote town.

By turns thrilling, poignant, and haunting, this is a story of two
lives touched by war and transformed by courage.
