Night blood

Iris has been apprentice to the dark witch Kiyra since she was young. Kiyra works for the Night lord, doing his dirty work and making potions. Iris has gone unnoticed until one day she starts developing unusual traits for a human, and her and Kiyra go hunting for a strong witch who might be able to help them discover what's wrong with Iris. When the Night lords best witch disappears for a few weeks he will start asking questions, putting Kiyra in a difficult situation. Does she tell him where she is and what she's doing, or does she wait until she knows what's wrong with Iris.
Along the way Iris will meet many friends but she will also discover what is wrong with the lands she lives on, and how her family history ties in with everything.
