Amazon says this about the book: Historian Lia Carrer has finally returned to southern France, determined to rebuild her life after the death of her husband. But instead of finding solace in the region's quiet hills and medieval ruins, she falls in love with Raoul, a man whose very existence challenges everything she knows about life--and about her husband's death. As Raoul reveals the story of his past to Lia, she becomes entangled in the echoes of an ancient murder, resulting in a haunting and suspenseful journey that reminds Lia that the dead may not be as far from us as we think.
Steeped in the rich history and romantic landscape of the Languedoc region, In Another Life is a story of love that conquers time and the lost loves that haunt us all.
