Somewhere near the end, there are about five pages I’ll just call the teardrop or droplet event. I read it on the Tube on my commute to work. By the time I reached the office, the impact was showing on my face. A colleague, clearly concerned, noticed before we’d even finished saying good morning. It stayed with me for a good few days. Very few books have managed to do that. There is a lot to critique: the overall style, the author’s biases, views that I don’t align with. I loved it anyway. The best book in the series for me.
