Can a Hero Save a Friend Who's Determined to Be a Villain?

Brother Ninja is the ultimate hero -- brave, skilled, and always ready to save the day. But when he rescues his best friend, Ace, from the terrifying Cliffs of Doom, things don't go exactly as planned. Instead of saying "thanks," Ace is furious! He's tired of being the sidekick and decides that if he can't be the hero, he'll become the greatest nemesis the world has ever seen.

After a lightning-fueled duel sends Ace tumbling into the Pit of Despair, he finds himself in the high-tech, gloomy Despair City. Armed with a new plan to take over the world and an army of quirky henchmen led by a man named Igor, Ace is ready for revenge.

But Brother Ninja isn't giving up on his best friend. With the "help" of his hilarious teammates -- Taekwondo Puppy(who's great at big words and tiny helicopters) and Karate Monkey (who might be better at snacks than sword fighting) -- Brother Ninja sets off on an epic quest into the heart of despair.

In this action-packed, laugh-out-loud adventure, Brother Ninja must face:

•

The Pit of Despair: A place where hope goes to hide, but Brother Ninja brings the party (literally -- he brought a birthday cake).

•

Hypnotic Villains: Ace's new powers might just turn the whole world against our hero.

•

The Power of Teamwork: Learning that being a hero isn't about the glory, but about the friends you make along the way.

Will Brother Ninja be able to save Ace from his own dark path, or has his best friend truly become his greatest enemy?

Perfect for fans of funny, fast-paced chapter books, Brother Ninja: Hero is a story about friendship, persistence, and why you should never bring a vegan protein bar to a sword fight.

J E Frank and E Y Frank team up to bring the most epic of adventures that the world could handle. Your kids won't wnat to put this down. Even for the beginner readers, this is an adventure that begs them to turn the next page.
