Emmy looks strange, labelled a Moon Rogue, a demon. Her days as an apothecary’s assistant to Madame Krodge are filled with hard work and abuse. Left on Krodge’s doorstep as a youngling, she knows nothing about where she came from. All her life she's wondered, who am I? Only friend Zecha is a male who wants to do what females do, and no one will accept him. Charo, a former slave, was discarded by her owner and left to die. No one under the Arc of the Sky wants them. All they have is each other. In the Masvam Empire, Prince Mantos Tiboli doesn't want to be the emperor but younger brother Bamdim does. Bandim plays with the dangerous magic of the Dark. He’ll stop at nothing to grasp the crown in his bloody claws, even if it means unleashing the power of the Dark on the world. Even if it means killing his only brother. When the Masvams attack their home, Emmy loses her home, her mistress, her life, but the changes bring more knowledge about her strange heritage than she ever dreamed of knowing. From humble beginnings, Emmy, Charo and Zecha must rise above prejudice to survive and claim their places in the world. Zecha must fight to be accepted. Charo must learn to trust again. Emmy must accept the strangeness of her true nature. Perhaps she is a Moon Rogue after all. Mantos, unwilling to rule the empire but unwilling to hand the crown to his brother, faces an impossible choice: command or be killed. Bandim must decide whether or not to embrace the power of the Dark. All must answer the question, who are you?
