Warrior of the Wind by Suyi Davies Okungbowa

From city streets where secrets are bartered for gold to forests teeming with fabled beasts, Suyi Davies Okungbowa's sweeping epic of forgotten magic and violent conquests continues in this richly drawn fantasy inspired by the pre-colonial empires of West Africa.
There is no peace in the season of the Red Emperor.
Traumatized by their escape from Bassa, Lilong and Danso have found safety in a vagabond colony on the edge of the emperor's control. But time is running out on their refuge. A new bounty makes every person a threat, and whispers of magic have roused those eager for their own power.
Lilong is determined to return the Diwi-the ibor heirloom-to her people. It's the only way to keep it safe from Esheme's insatiable desire. The journey home will be long, filled with twists and treachery, unexpected allies and fabled enemies.
But surviving the journey is the least of their problems.
Something ancient and uncontrollable awakens. Trouble heads for Bassa, and the continent of Oon will need more than ibor to fix what's coming.
