The novel brings together a looming environmental crisis, global warming, and its effect on monarch butterflies, and a family network also at risk. The parallels were there and I enjoyed the human relationships as much as the naturalist side of the book. Our book group found a lot to talk about. Other themes included \\\"the haves and the have nots\\\", \\\"education\\\", \\\"parenting\\\" and \\\"marriage\\\". I would recommend the book to other book clubs.
