DiMartino has created a fantasy world in which artists have a Genius, an actual physical animal like the daemons in The Golden Compass. The ruler of the land is a tyrant who has made it illegal for anyone to have a Genius and has seized and destroyed all but her own. The artists who lose their companions become Lost Souls, eventually going mad or wasting away. But there are a few children who have a Genius and live in hiding. They undertake a dangerous quest to find the Creator's Sacred Tools, the artist's tools used to create the world, before Queen Nerezza can claim them and use them to remake the world as she chooses.
As in most fantasy adventures, there are villains, a quest, and young heroes who are still learning what they are capable of. Just imagine - a world where artists can manifest physical forces with the power of their minds, drawing forms of Sacred Geometry to create defenses and attacks. The pen truly is mightier than the sword in this case. The children all have different backgrounds, and there are boys and girls in the group so that readers of both genders feel included. A mix of danger, adventure, personal growth, and even a little mysticism about the Wellspring of creativity all come together to make an entertaining and enjoyable tale. There could easily be more books featuring these characters.
I read an e-book provided by the publisher through NetGalley.
