Time of the Sorceress — Krista Walsh

I finally put my past behind me only to find my future at risk. One more hunt, I promised myself. One more death, and then I could hang up my guardian's cloak and put my magical self out to pasture. But with every enemy I take down, another one strikes. And this time they hit me where it hurts—in my bond with Emrick, the servant of Death who holds my heart and my immortality. For the first time in almost nine hundred years, my life hangs in the balance. But I have friends now, a family, a reason to keep going. If I don't discover who's hunting me— and fast—everything I've built for myself will burn.
