Ella, a contemporary American, struggles to assimilate in the small medieval village where she and her husband have settled. Her genealogy research leads her on a fateful trail to Switzerland. The intertwining story (400 yrs earlier)tells Isabelle's tragic part in her family's migration during the Protestant reformation...a time of Calvinist sects trying to break away from the Papacy. Superstition, gossip and tragedy follow both woman. I love historical fiction so wish Chevalier had told more and not left me with so many questions. As with the "Girl with a Pearl Earring", I felt she just skimmed over the surface with an "outline" for what could have been a great novel.
