Jared, Simon, and Mallory Grace move into an old Victorian house and right away they start hearing noises from the walls. Simon gets excited because he thinks it is a squirrel. While exploring around the house, Jared finds a mysterious book (an informative field guide) written by a relative a long time ago. The book describes strange creatures and how to deal with each of them.
When Jared is blamed for mischievous events that occur around the house, he tries to find out what is really going on, and discovers one of the creatures described in the book.
Rating: 10/10. I absolutely loved this book. It was a fun introduction to a very awesome story line.
