In twelve-year-old Giacomo's Renaissance-inspired world, art is powerful, dangerous, and outlawed. Every artist possesses a Genius, a birdlike creature that is the living embodiment of an artist's creative spirit. Those caught with one face a punishment akin to death, so when Giacomo discovers he has a Genius, he knows he's in serious trouble. Luckily, he finds safety in a secret studio where young artists and their Geniuses train in sacred geometry to channel their creative energies as weapons. But when a murderous artist goes after the three Sacred Tools—objects that would allow him to destroy the world and everyone in his path—Giacomo and his friends must risk their lives to stop him.

In Warrior Genius, author Michael Dante DiMartino delivers rich settings, memorable characters, and edge-of-your-seat action, just as he did in his hit animated show The Last Airbender. Fans will be thrilled with this new adventure! For years, Supreme Creator Nerezza has used fear and violence to rule her empire, seeking to eradicate anyone with a Genius. Then, twelve-year-old Giacomo emerged from hiding and joined a young generation of fellow artists paired with Geniuses. Together, they began a rebellion against her. Now, Giacomo has something Nerezza desperately wants—the Compass, one of three powerful objects known as the Sacred Tools. Possessing all three would allow Nerezza to spread her tyranny worldwide. After a near-fatal showdown, Giacomo and his friends escape to the empire of Rachana, a society long feared for its mighty warriors and their horse-Geniuses. But a dark and ancient force threatens the horse-Geniuses with extinction, and Giacomo discovers he is the only one who can stop it. With the help of his Genius and great friends, Giacomo struggles to keep the Sacred Tools from falling into the wrong hands and find a way to protect the Rachanan people—before Nerezza finds him.
