Of sand and malice made : a shattered sands novel / Bradley P. Beaulieu.

Çeda is the youngest pit fighter in the history of Sharakhai. She's made her name in the arena as the fearsome White Wolf. None but her closest friends and allies know her true identity. But this all changes when she crosses the path of Rümayesh, an ehrekh, a sadistic creature forged aeons ago by the god of chaos. The ehrekh are desert dwellers, but for centuries Rümayesh has lurked in the dark corners of Sharakhai, combing the populace for human "jewels" that might interest her. Some she chooses to stand by her side, until she tires of them and discards them. Others she abducts to examine more closely, leaving them ruined, worn-out husks. Çeda flees the ehrekh's attentions, but that only makes Rümayesh covet her more. Rümayesh grows violent, threatening to unmask Çeda as the White Wolf--but the danger grows infinitely worse when she turns her attention to Çeda's friends. As Çeda fights to protect the people dearest to her, Rümayesh comes closer to attaining her prize, and the struggle becomes a battle for Çeda's very soul.
