Metru NUI: City of Legends (Bionicle)

Summary: The Official Guide to Metru Nui
Review: My son is a Bionicle fanatic and likes this a lot (well, anything about Bionicles would make that cut). It is very similar to "The Official Guide to Bionicle," but for Metru Nui instead of Mata Nui. It fills in background details about each Metru.
