In 12-year-old Giacomo's world, art is powerful, dangerous, and outlawed. When Giacomo discovers he has a Genius--a bird-like creature that is the living embodiment of an artist's creative spirit--he knows he's in big 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 create an indestructible army--he finds himself on a dangerous quest to stop him.
Magic, mystery, and math come together in this enthralling, page-turning new series from the co-creator of Avatar: The Last Airbender.
