This book is a new take on the hardboiled detective genre. Remy Chandler is a P.I. who also happens to be an angel. Yes, an angel. He chose to leave Heaven and live on Earth in human form. However, he does have super-human strength, invisibility, and can communicate with any living thing. The interactions with his dog, Marlowe, are some of my favorites in the book. Even though this book is (obviously) based on Christian doctrine, I would not classify it as "religious fiction". I would recommend it to fans of the Dresden Files series by Jim Butcher or anyone looking for something a little different.
