The Wraith’s Corruption by J.A. Stowe

Darkness calls … but it comes at a cost.
Ari’s price was his life.
What will mine be?
It’s been months since the battle at the well of Draqaar. Since Sebastian broke open the Aether, draining it to fuel his undead army. But the Aether still hasn’t recovered. In fact, it’s getting worse. We’re running out of time to find the missing reaper, Enoch, and Ari’s clue leads me to believe he’s somewhere on Earth.
Entire hunter compounds are disappearing. And it has the stench of Sebastian’s corrupt magic all over it. To face him, we’ll have to seek unlikely allies. Let’s just hope they give me a chance to explain myself before shooting me on site.
But dark magic is growing inside me. It promises powerful magic. With it, I can finally match Sebastian’s power. But it comes at a cost. Ari’s price for his corruption was his life. What will my price be?
