Akata Woman (The Nsibidi Scripts) by Nnedi Okorafor- Hardback

Akata Woman is the New York Times bestselling third book in the series that started with Akata Witch, named one of Time magazine's "100 Best Fantasy Books of All Time" and "100 Best YA Books of All Time," from award-winning author Nnedi Okorafor.
"In this series, Okorafor creates a stunningly original world of African magic that draws on Nigerian folk beliefs and rituals instead of relying on the predictable tropes of Western fantasy novels."
—Time magazine

From the moment Sunny Nwazue discovered she had mystical energy flowing in her blood, she sought to understand and control her powers. Throughout her adventures in Akata Witch and Akata Warrior, she had to navigate the balance between nearly everything in her life—America and Nigeria, the "normal" world and the one infused with juju, human and spirit, good daughter and powerful Leopard Person.
Now, those hard lessons and abilities are put to the test in a quest so dangerous and fantastical, it would be madness to go...but may destroy the world if she does not. With the help of her friends, Sunny embarks on a mission to find a precious object hidden deep in an otherworldly realm. Defeating the guardians of the prize will take more from Sunny than she has to give, and triumph will mean she will be forever changed.
