The Red Heart of Jade by Marjorie M Liu
Dirk and Steele book 3. Loved, loved, loved it. More shape shifters and out of this world crimes that they seek to solve. Characters have a real depth to them and their crossing through novels add to the stories. The hero being stalked by a fire breathing dragon is just sublime. The underlying story about the founders of this agency, Dirk and Steel threads through connecting the family in this and opposing it.
Keep it and reap it.
