Overall it is good. I got tired of, lost patience with, the whining of the main character. It is a good and important subject in the background. There is good foreshadowing and the author does clean up most of the loose ends at the end, but leaves us with one dangling issue.
I wonder what this book would have looked like if there had been joint protagonists, the husband and wife. I was not empathetic with the husband and I think his character would haven better without the endless poor pitiful me/us what-iffing and have the wife be the what-iffer in a more interesting way (the subject she was an expert in).
I understand why the husband wasn’t forthcoming on some important matters, but I found myself yelling at him, “just tell her already!!!” But we didn’t get to hear his wife ‘s processing of the world.
It is cool how the ethical and practical issues wind themselves around “what to do.”
