How rare is this book?

The LEGO Ninjago book in question appears to be quite rare, as the original poster has been unable to find any information about it on Bricklink.

The user, /u/Zippy1kanobi, shared their difficulty in locating information about the Ninjago book. They mentioned searching on Bricklink, a popular online marketplace for LEGO products, but found no listings or details about the book. This lack of information suggests the book may be a limited release, a promotional item, or simply very uncommon.

Without further details about the book, such as its title, ISBN, or any distinguishing features, it's difficult to determine its exact rarity or value. However, the inability to find it on a platform like Bricklink, which catalogs a vast array of LEGO-related items, strongly indicates that it is not widely available.

If you are a collector, you might want to keep an eye out for this rare book, as it could be a valuable addition to your LEGO Ninjago collection.
