Beasts Made Of Night by Tochi Onyebuchi
In a dark and fantastical city, the young and impoverished are employed as sin-eaters, known as aki, who consume the sins of the wealthy, manifesting them as beasts made of night. These sins take the form of Inisisa—sin-beasts that the aki must slay to absolve the guilt of the sin's original owner, at the cost of bearing the sin's tattooed image on their own skin. The story follows one such sin-eater, a talented but troubled young man, who finds himself embroiled in political intrigue and a deeper, more dangerous plot that threatens the very fabric of his society. As he grapples with his own identity and purpose, he must navigate a treacherous world of power, magic, and monsters—both human and created.
