I've changed my rating of this from three stars to four and then back to three again, I just can't decide, so let's go with 3.5.
Unpopular opinion from scanning the rest of the reviews but I just don't find this books ending, and the end of the trilogy itself, at all satisfying. The ending surprised me certainly, and wasn't at all how I expected it to go. I found it quite disheartening and wasteful.
I don't understand why the church that Harry (the father) was so passionate about and dedicated his very short life entirely towards, even when finishing the church led to his death - had to become partial ruins in his sons lifetime and at the end of this book. In the outstanding first book, Harry the father said that he wanted the church and his creation to stand the test of time, and light up in the most beautiful ways that Parteger took great pains to describe over and over again, for hundreds of years to come, long past his existence. He wanted the faces of the people he'd known and carved out in the church to be there long after everyone had forgotten who they all were, and for people to still look at them and wonder if they were ever supposed to be anyone. And yet within his own sons lifetime, just 19 years on from his death, events have culminated with Parfois' destruction and the church being torched and then given over to waste along with the rest of the castle. Villagers from nearby who's home and livelihoods have been ruined then use the fallen stones and masonry to rebuild their own homes, and Harry the son travels through the villages and sees parts of the church everywhere, and even a little boy chiselling away at a piece of the church's stone, making a new carving. The only reasoning I can give for this is that Harry the father was greatly a man of the people, as seen in his running away from his noble family when young, becoming a Mason and having a craft, and notably, helping the villagers reap their corn and get in their harvest lest it waste - and therefore as Parteger says at the very end of this book, by the church stones being used all over the countryside to rebuild, Harry the father was now everywhere in the land.
But I don't like it. It doesn't sit well with me at all. I thought it wasteful and the church should have remained, seeing as it was the whole physical tie of the trilogy, the physical testament of not just Harry the father's work, but all the people of that time and place in history. Especially seeing as Harry the father, Ralf Isambard and Madonna Benedetta came to rest there.
Positive points for the book are the excellent portrayals of Ralf Isambard and his condition, and the reconnection between him and Madonna Benedetta. However, I'll stick with the first book for satisfaction.
