This is book 15 of the "Brother Cadfael" series.

This note contains spoilers for the book.

The fifteenth Brother Cadfael book. Twisty, and involves fewer murders than originally claimed. And a rather nasty bitter old woman, who's apparently been like that forever.

A brother injured in a construction accident (fixing the roof after a major snow collapsed it partially) miraculously survives, sets out to clear his conscience, and discovers that everything he knows is wrong; or at least that the events that dominated his life were lies. And comes to accept his vocation even more happily.
