This is the third Tracy Chevalier book I've read. As always, it's a well-written piece.
In this outing, we have two stories: those of Isabelle du Moulin and Ella Tournier. They're related, but separated by about 400 years. Sometimes, it feels as though Chevalier is trying to imply that this is a reincarnation tale, but it really seemed more like parallel lives to me. Both are midwives, and both are somewhat obsessed with a color referred to as "Virgin blue," a costly pigment made with ground lapis lazuli that was used in 16th C. paintings.
In any event, the chapters alternate between the two women's stories, showing troubled marriages, thwarted ambitions and more.
I enjoyed the book and would recommend it to fans of historical fiction.
