Masters of Spinjitzu: a new force to save the world!
The next chapter book in the Ninjago series!
Cole is the leader of the team. As the Earth Ninja, he is (perhaps unsurprisingly) the most grounded of the four. And the strongest. There is no physical challenge Cole cannot overcome. Now is his chance to use his skills to save the world!
Sensei Wu has gathered a powerful team of ninja warriors. Now he must train them in the ancient art of Spinjitzu. If he fails, Lord Garmadon and his evil skeleton warriors will destroy the land of Ninjago and all of its inhabitants.
Solid and steady, Cole—Ninja of Earth—was destined for the challenging role of leading his fellow ninja on their dangerous missions. Now it's up to Cole to unite the team while utilizing their different strengths. But can Cole keep each ninja's ego in check before someone gets hurt . . . or worse?
