They cant keep you.

Sierra successfully brought magic back to the world, but its left her with two big problems.

First, now she needs to steal Nariel back from the exile the angels forced him into to save their worlds. But shes also in dire need of magic weapons, because the mages are doing everything in their power to take her magic and her life.

Both of those needs take her to the world of demons, where Nariel has his own ideas for how Sierra can get her hands on enough power to protect both of their worlds.

With mages coming after her with magic weapons of their own, Sierra needs every bit of magic she can wield. But she messed up before, and badly. So how can she trust herself to wield more power than any human ever has when failure would cost Nariels life, too?
