This book is an excellent follow up to A Discovery of Witches. I was afraid that the sequel would not live up to my expectations that have been building for a year since I read the first one. Luckily, that fear was incorrect.Shadow of Night starts immediately where Discovery left off and begins to weave in various historical figures throughout the book right up until the end. In the first book there were many descriptions about the food and wine with great detail, in this one the detail is in the historical aspects. I loved the historical features and characters in this book and felt that just as the descriptive food and wine gave the first book authenticity so did the historical features here.I loved getting glimpses of various historically famous places and people. Like any good book it made me want to go find out more. I have no doubt I will be reading about Christopher Marlowe and Walter Raleigh due to this book.The relationship between Matthew and Diana also did not disappoint. There was both romance and intrigue along with more secrets that hadn't been revealed before. There was enough suspense and action to keep my interest and balance out the romance.I loved this book, just as much as the first one. These are the only books I will own in both audio and Kindle version because the narrator is so amazing. I will be waiting on pins and needles for the third book. Undoubtedly it will go in my favorites shelf as well.
