She appears to be Caucasian. The main description of her...
she's shorter than many others, but has "heavy layers of muscle" (1.30). She also has "black curls [that] reached to her shoulders" (1.30) and a mouth "wide and expressive to the point of being sensuous, curled slightly at the corners in a slight smile which might be cruel or merely playful" (1.30) According to the narrator, she "might well be considered beautiful" (1.31).
