Kingsolver's characters and settings seem to stay with me, and I think that will be particularly true for Dellarobia and her farm in Appalachia. The arrival of the butterflies sets into motion a series of events and realizations for Dellarobia. Her situation and the butterflies' are both pretty bleak but not without hope. There's a lot woven into this story - marriage, in-laws, parenting, religion, and living in poverty, along with some commentary on journalism and science. The climate change message was effective and provided new insights for me, but it was a little overbearing at times. But it was thought-provoking and most Kingsolver fans should like it.
