Empire of Sand (The Books of Ambha)
From the publisher: "A nobleman's daughter with magic in her blood. An empire built on the dreams of enslaved gods. A captivating, Mughal India-inspired debut fantasy. The Amrithi are outcasts; nomads descended of desert spirits, they are coveted and persecuted throughout the Empire for the power in their blood. Mehr is the illegitimate daughter of an imperial governor and an exiled Amrithi mother she can barely remember, but whose face and magic she has inherited. When Mehr's power comes to the attention of the Emperor's most feared mystics, she must use every ounce of will, subtlety, and power she possesses to resist their cruel agenda. Should she fail, the gods themselves may awaken seeking vengeance."
