Echoes from the Hills — Barbara Ferry Johnson

He was Ryan Middleton, a man without a past.
Wounded by the Germans in the fields of Belgium, he lay sleeping in a coma, lost to the world. Only Alys Prevou, a young mother already widowed by the war, could save him and teach him to live anew. Sheltered and blessed by the coming peace, their tenderness for each other would blossom and grow. But what would happen when Ryan remembered his American wife? What would happen to alys when Ryan's memories flooded back, and wiped away their months of love from his mind, perhaps never to return?
