The Dancing Ninja (Hardcover) (ISBN-13: 9781736888209)

Kobee is a master ninja...or so he thought. How could his sister, Kai, be better at leaping, spinning, and balancing than him? She's just a ballet dancer and doesn't even know how to do a roundhouse kick. Kobee becomes very frustrated because nothing he tries is working. Follow Kobee as he does something out of his comfort zone and takes a dance class to perfect his ninja skills.
