Demons (Darkness, 4), Paperback

It's been a long road, but Sasha has finally claimed her role as the least knowledge mage in history. She's also acquired a new, incredibly grumpy bodyguard, and a spunky new BFF. With her team by her side, she learns the ropes of this new profession. Her experience level is about to be fast-tracked, however. On a routine trip to check out a perimeter breach, she encounters a hideous demon called by an experienced magic worker. It is this terrifying discovery that unlocks a deeper problem: Stefan's troubled past and the reason he gravely mistrusts the Mata. While Sasha struggles to fight the physical demons, Stefan struggles to fight the demons of his past. If he fails, his future in Sasha will be lost.
