This is the best book in the series so far. Toby's search for a changeling with uncontrolled power is action packed and well written. As the book opens, she is still grieving over events in the previous one and worrying her friends with her reckless behavior. Once she is handed the case, she hits the ground running, trying to prevent a disastrous outcome. I was extremely happy to find Tybalt a major presence in this book. I was also happy to see growth in Toby; she acknowledges her ties to her friends and this is the first book in which her journey does not seem isolated and solitary. I will definitely be reading the next book.
