The Fan's Guide to the Spiderwick Chronicles by Lois H. Gresh is a guide to the popular fantasy series by Holly Black and Tony DiTerlizzi. The first chapters of the book summarize all of the Spiderwick Chronicle novels. The book also gives a useful explanation of all the characters and creatures found in the novels. Gresh shares her opinion on the books and situations that happen in them. She goes into a brief, but detailed description of the three main characters: Jared, Simon, and Mallory Grace. Since the Spiderwick novels are about fairies, Gresh also shares some other fairy legends, which she ties into her explanations. For instance, she mentions a lot of Irish myths that were not even remotely mentioned in the Spiderwick novels, and I thought that these legends were interesting and provided a deeper layer of context. A particular feature that I enjoyed in the book was the "fast fact" questions at the end of each chapter. Each question deals with something in the chapter, and it was cool to read the questions (even though the answers are quite simple).
