Reaping darkness, the Shadow slicked steel with judgment and danced with death…

Sixteen-year-old Aza inherited the power of shadow to rid the land of evil as Odriel’s cold-blooded assassin. With her growing strength, Aza discovers the Shadow Plane—a realm of wraiths where screams haunt the winds, calling to her. Although her father forbids her from entering the dark realm, Aza can’t ignore the beckoning whispers.

When a dangerous new breed of monster attacks, Aza believes the Shadow Plane holds the answers they need to defeat them. With the unwanted help of a snarky cat and a cursed beast, Aza seeks out the monastic Wraith-Called for answers. But the deeper Aza delves into the dark realm, the further she drifts from the world she knows.

As Aza uncovers evils new and old, she must decide if the ends really do justify the means… and how many lives she’s willing to pay.
