Shadow of Night by Deborah Harkness

In all series there are the books that serve as the bridge to the rest of the series. This was definitely a "bridge" book but despite that, I found it thoroughly enjoyable. I loved the new characters introduced in this one and I enjoyed Diana's educational journey while she learned to use her gifts. I also really liked the historical element. Historical fiction is still my favorite genre so I love it when characters I enjoy visit another time. I'm looking forward to reading about how Matthew and Diana use what they learned in the past against their enemies of the present.
