BIONICLE Adventures #9: Web of Shadows is the ninth novel in the BIONICLE Adventures series published by Scholastic. It serves as the novelization of the movie BIONICLE 3: Web of Shadows and was released a few months prior to the release of the movie. It also contains an appendix explaining the history of the Toa Hagah. The entry on Bohrok from the BIONICLE Encyclopedia is included as a preview for that guidebook.
Greg Farshtey dedicated this book to his wife, but the two of them were not yet married when the dedication was written. The intention was that the book's release would coincide with their wedding in August, but the book was released early.
