The main character in this book is a Crat named Echo. He lives in Malaisea, the unhealthiest town in Zamonia. He can speak any language. He has to sign a contract with Ghoolion, the alchemaster. In return for feeding Echo, Ghoolion will render down his fat on the next full moon. In order to render his fat down though, Ghoolion will have to kill Echo. I rate this ten Leathermice out of ten.
