In a world teetering on the edge of chaos, Sienna Nealon is the unrelenting force keeping the worst of humanity in check. But after years of sacrificing everything—her freedom, her relationships, her very soul—to hunt metahuman criminals, the cost is catching up. As she delivers justice with a ferocity that borders on vengeance, Sienna grapples with a chilling truth: she may never escape the cage of her own making.
