I am absolutely loving this book. I didn't realize when I checked it out, but it's set in the fiction Barchester of Anthony Trollope, and the author has done several call-outs to Trollope's creation. The main character lives in a converted cottaged created from two of the rooms in the almshouse that was at the center of The Warden, and Septimus Harding has been mentioned by name! It's just delicious!
Combining the Arthurian legendarium with the Chronicles of Barchester? The Grail at Barchester Cathedral? OMG, sign me up.
