I love this series. Amazon has been recommending this series to me for years and I never bought it. I was sure I would not like it because it was a historical setting. This book was great almost like the movie The Body Snatchers. I loved how our threesome work together to solve this mystery. I can't say enough about how the women are written in this book as strong and likeable. In so many MM books this is not true. Christine is wonderful and fearless even when she is scared. Whyborne is still my favorite character. I love Griffin and Whyborne together. The horror in this book was great. The action as they defeated the creatures was wonderful. I loved this book.
