Used book – The Winter Ghosts, Kate Mosse

The Great War wiped out an entire generation, cut down in the prime of life... In the case of Freddie Watson, a young Englishman from Sussex, it took his beloved brother. Haunted by this loss, he wanders aimlessly, not knowing how to escape this nagging pain. In the winter of 1928, Freddie was traveling in the South-West of France when his car left the road. Still in shock, he stumbles into the woods and finds refuge in an isolated village. There, during a kind of medieval festival, he meets Fabrissa, a beautiful young woman who is also mourning her lost loved ones. During the night, Fabrissa tells Freddie a strange story. The next morning, when he wakes up, Freddie wonders if it was all a dream. Yet there is indeed a mystery linked to the village's Cathar past...
