Wonder Woman's home island of Themyscira holds many surprises...the most adorable having floppy ears and long tails! Kangas are companions and partners of the Amazons, beloved steeds and protectors of their bonded warriors. And on the island, a school exists to train the next generation of kangas for the many battles and challenges of the future.

And it's finally here--Bonding Day, the long-awaited time when Amazons are matched up with newly trained kangas to make the perfect pairs. This special event only happens once every twenty years, but this Bonding Day is unlike any other because this is the year when Princess Diana--the only teenager on Themyscira--will choose a kanga for the first time.

Jumpa has been training hard to compete in the Tournament of Kangas, where all the kangas get to show off what they can do. She knows that she has what it takes to match with the Princess. The only catch is her friends Skippa, Rooth, Goldie, and Big Red are all determined to do the same--and the competition is fierce.

When Ares arrives on the island with a threat that forces the festivities to be cancelled, Jumpa must convince her friends to work together for the good of Themyscira, and to protect the Princess they admire.
