When Akuany and her brother are orphaned in a village raid, they're taken in by a young merchant Yaseen who promises to care for them, a vow that tethers him to Akuany through their adulthood. As revolution begins to brew, led by the self-proclaimed Mahdi, Sudan begins to prise itself from Ottoman rule, and everyone must choose a side. Yaseen feels beholden to stand against this false Mahdi, a decision that threatens to splinter his family. Meanwhile, Akuany moves through her young adulthood and across the country alone, sold and traded from house to house, with only Yaseen as her intermittent lifeline. Their struggle mirrors the increasingly bloody struggle for Sudan itself - for freedom, safety and the possibility of love. River Spirit illuminates a fraught and bloody reckoning with the history of a people caught in the crosshairs of imperialism. This is a powerful tale of corruption, coming of age and unshakeable devotion - to a cause, to one's faith and to the people who become family.
