Every act of revenge demands a sacrifice. She has no idea what hers will cost.
After losing her twin sister, Damara, Cailyn is consumed by grief, haunted by guilt, and plagued by a darkness growing stronger with every passing day. The shadow magic she once feared is no longer under her control, and whispers from the dead suggest her sister's fate may not be as final as it seems.
As the ancient wards protecting humanity begin to fail, demons creep closer, old prophecies awaken, and a forgotten evil stirs beneath the ruins of a broken world. With the unwavering support of Ayden, two unlikely allies, and a mysterious newcomer who knows far more than he should, Cailyn sets out on a path fueled by one purpose alone-revenge.
But vengeance has a price.
The closer she comes to the man responsible for Damara's death, the more the darkness within her awakens. And if Cailyn finally claims the revenge she's willing to die for... she may unleash something far more terrifying than her own wrath.
