Tread of Angels

In the mining town of Goetia, the world is divided between The Fallen, descendants of demonkind, and The Virtues, the winners in an ancient war. Celeste and Mariel are two Fallen sisters, bound by blood but raised in separate worlds. Celeste grew up with their father, passing in privileged society, while Mariel stayed with their mother in Goetia's slums. Celeste is wracked by guilt for leaving her sister behind, and when their father dies, she becomes Mariel's fiercest protector. But their lives are upended when Mariel is arrested for the murder of a Virtue. Determined to save her sister and prove her innocence, Celeste turns to her ex-lover, a former general in the armies of Hell, for help. Soon Celeste is making her own deals with devils and angels alike to prove her sister's innocence. However the journey to discover the truth threatens to become more than Celeste ever bargained for.
