I read this book because I saw a review that said it was a "sophisticated thriller." The central premise is a little far-fetched for me: otherwise extinct creatures living at a remote chateau in France are protected by a secret society that dates back thousands of years. If you're willing to overlook this bit of improbability, the book is fast-paced and easy to read. There were some potentially interesting characters that the author did not develop nearly enough and I would have liked to have seen the ecology theme explored in more depth. Still, I enjoyed the book and would recommend it.
