I really enjoyed this book; it was great to return to Deverry, and catch the Easter Eggs to previous books that she has sprinkled throughout (Easter Eggs/historical references, take your pick).
Two things I would have very much liked to have in the book, however:
1) A Map. I've never been 100% clear on the geography of Deverry and the environs, and a map would've helped me visual what's going on a lot better.
2) A dramatis personae. We're dealing with entirely new characters, almost all of whom have names that are used in both the common and familiar form. A list of characters and a sentence about who they are would've helped keep them straight... especially when their names are similar.
