The Spiderwick Chronicles is a movie in cinemas in the United Kingdom (Scotland, Wales, England and Northern Ireland) at the moment and maybe in other countries as well but I don’t know. The story is based on some books about the children in A6 size (when folded like a book) and so are these other extra books. This is one of the extra books about the three children and this is the first book of the additional books. Here is a quick description of the children:
Jared Grace – Simon is his twin, though Jared is much more quick-tempered and bold.
Simon Grace – he is quiet and kind; he loves animals, and has quite a lot of pets.
Mallory Grace – Jared and Simon's elder sister, who is a fencer, an ability which comes in handy when defending herself.
