However, there is a fourth book, "The Spiderwick Chronicles: The Griffin's Guide to the Hidden World," which is part of a series of spin-off books that expand on the world established in the original trilogy.
The setting of "The Griffin's Guide to the Hidden World" is not explicitly specified, but it is likely to be set in the same world as the original trilogy, specifically in the "Hidden World" of magical creatures. This spin-off book is primarily focused on the Griffin's perspective and experiences, rather than on the original characters.
It is important to note that this book is written in the form of a field guide, similar to the original "Field Guide" book. The story is presented through the Griffin's point of view and his experiences, with a focus on the magical creatures that populate the Hidden World.
Therefore, while the setting of the "The Griffin's Guide to the Hidden World" is not explicitly stated, it is likely set in the same magical world as the original "Spiderwick Chronicles" series, with a particular focus on the Hidden World.
