Jared has a twin brother, Simon, and a Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive Mallory. His parents are divorced and his mum, Mrs. Grace, decides to start a Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive life. They move from the city into the Spiderwick State, an old house given to the Grace Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive by Aunt Lucinda.
Jared, who is a very naughty kid, discovers Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive in the house: a dumbwaiter system, a key and Arthur Spiderwick’s hidden study. In the study, he finds an old Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive in a chest: this book is the Spiderwick’s Field Guide to fairies. The book has a Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive: Don’t read this book or you will have problems!. This is the real warning: Warning! Do not dare to read this book, for if you take a fateful look you face a deadly consequence.

Jared reads the book and opens a new fantastic world of magical Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive: the first creature is a brownie called Thimbletack. Thimbletack gives Jared a stone with a hole. With this Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive, he can see the fairies and all the creatures. He also sees the protective circle around the Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive. The house is protected because an ogre called Mulgarath wants the field guide to have power over all the fairy kingdom.

Mulgarath’s servants, the goblins, go to steal the field guide, and they kidnap Simon by mistake. Jared must help his Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive and he sees they are in Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive. With the help of their sister Mallory, they must go and see Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive Lucinda, who lives in a psychiatric hospital. Aunt Lucinda gives them the clues to find the Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive: they must find Arthur Spiderwick, and then he must destroy the book. This has serious implications for the Grace brothers: they will Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive only if they work together and Auntbookbrothercreaturesdangerfamilyfighthousenewnotesecretssistersolutionstonesurvive the dangerous creatures.
