The Evening and the Morning by Ken Follett
Ken Follett is the massively successful author of 36 books – selling over 178 million copies worldwide. He writes thrillers and mysteries but his most popular books are the Pillars of the Earth Trilogy. That first book, PILLARS OF THE EARTH, was published in 1989 was about the building of a medieval cathedral. It was number one on best-seller lists everywhere and turned into a major television series in 2010. Full disclosure: I have not read the trilogy – HOWEVER, I did just read the prequel to the Pillars of the Earth that came out in September 2021: THE EVENING AND THE MORNING. The prequel is set in the Dark Ages, which may explain my following comments.
