Fired Up! (subtitled Brick Adventures) is a presumably canon Ninjago book. It is written by a children's book author named Meredith Rusu. It includes three stories set between Season 9 and Tales from the Monastery of Spinjitzu.
This all-new chapter book includes three original stories about the ninja! When Master Wu calls his old student Kai, he has a special mission for him: it's time to go BACK to his old ninja monastary and fix it up. That might sound boring, but what starts as a simple chore ends up as a ninja training jungle gym extravaganza! Plus, two more stories about classic ninja Zane and Lloyd! Contains full-color illustrations throughout three action-packed, easy-to-read adventures.
- In this book, the Monastery of Spinjitzu is rebuilt by the ninja, explaining its return in Tales from the Monastery of Spinjitzu and March of the Oni.
