Query: Very good

This book was really good. It was very interesting. It was, however, a bit more violent and sad than Tamora Pierce's others (exept for maybe Lioness Rampant), as it is about murders. That does not make it bad, but if you are thinking of reading it, you should know that before hand. I really liked this book, and i hope to read the next one as soon as it comes out.
