The Book of Killowen: Erin Hart's Nora Gavin/Cormac Maguire novel. I really enjoy this series. It always is based on a historic event, has great research and well written archaeology. It captures time and place very well.
The Cove by Ron Rash. The "New York Times" bestselling author of "Serena" returns to Appalachia, this time at the height of World War I, with the story of a blazing but doomed love affair caught in the turmoil of a nation at war.
