Shadow of Night

More than 90 percent of this book takes place in the 1500s, and while I preferred the world built in A Discovery of Witches, this book really explores some of the central questions of the book and helps move Diana along in her development as a witch.

A few things that I found a bit problematic are time continuity/continuum and the fact that the very reason for going back to the 1500s was pretty significantly downplayed. That being said, I can't wait to get started on book 3!
