"They can't keep you." Sierra successfully brought magic back to the world, but it's 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 she's 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 Nariel's life, too? Take Back Demons is the second book in Diamond Universe: Sierra Walker, a fast-paced, action-packed urban romantasy series spanning the modern world and also other worlds full of magic, with a shadow-wielding demon boyfriend and a heroine who never quits no matter the odds and just goes harder as they fight to change the universe for everyone. Expect the heat level to escalate dramatically in each book.
