The Field Guide ( The Spiderwick Chronicles )

After moving into their dilapidated family estate, siblings Jared, his twin brother Simon, and their older sister Mallory experience unexplained occurrences. Upon exploring the attic, Jared finds a mysterious, handmade field guide authored by their great-great-uncle, Arthur Spiderwick. This book documents a hidden, parallel world filled with faeries, brownies, boggarts, and goblins. Against the book’s warnings, Jared opens it, unintentionally drawing the ire of supernatural creatures who will do anything to keep their magical realm a secret.
