Adia Kelbara and the circle of shamans
(Book)

Life is tough for twelve-year-old orphan Adia. Her aunt and uncle believe she's an ogbanje, a demon-possessed child that brings misfortune wherever they go, and Adia can't disagree, especially when she suddenly manifests mysterious powers that she can't control, causing an earthquake in her village. So when Adia is offered a kitchen apprenticeship at the faraway Academy of Shamans, she flees with nothing but a pouch of change, her cat Bubbles, and the hope that someone there can figure out what's wrong with her, and fix it. But just as she's settling in, Adia stumbles upon a shocking secret: Unlike her, the kingdom's emperor really is possessed, by a demon more wicked than any other. And he's on his way to the Academy for a visit. Joining forces with a snarky goddess, a 500-year-old warrior girl, and an annoying soldier-in-training, Adia must travel through hidden realms to exorcise the emperor and save her kingdom. But to succeed, she first must come to understand the powers inside her. . . . The fate of the world hangs in the balance.
