Shadow of Night  - Deborah Harkness I loved this book for the amount of factual details Ms. Harkness included. Once again, her research was impeccable. I loved recognizing the alchemic and spiritual/metaphysical elements that are woven throughout this entire book, since I am an avid student of these subjects. The love story between Matthew and Diana is one of legend, and experiencing history through their eyes, was a very enjoyable trip.I cannot wait for the next book in the series.
