LEGO Ninjago: Kai: Ninja of Fire (Chapter Book #1)
Will Kai be the greatest warrior ever known? Maybe, if he ever listens to Sensei Wu long enough to complete his training! He's stubborn, he's reckless, and he might just save the world.!
Beginning with a quick challenge for the ninja to solve and then moving on to a full-scale adventure, this action-packed book is really two Ninjago stories in one!
