They're the Supernatural Protection and Investigations Agency. They try to stop what roams in the night from eating you. In this book they have to find a cluster of diamond eggs, stolen by Harpies, that can cause complete chaos in the supernatural community. Mostly by unmasking supernaturals, removing their glamour and exposing them to the world. In a city as big as New York with a large supernatural community, that's a lot of rioting, burning torches and pitchforks once the humans learn what lives alongside them.
Once more it's down to the human seer Makenna and her human partner Ian to solve the mystery and save New York - with the help of the SPI team. I really love these books. There's nothing Shearin has written that I haven't loved. Shearin is a fantastic writer, her characters are so evolved you feel sad even when a walk-through character dies. This book was a fun ride, I was sad when it was over. I like the way the characters and the stories are developing. I cannot wait for book three - although I hope it has better cover art.
