Mary Grace Liu. 18. Chinese-American. High school senior. Works part-time at Old Lady Dot's diner. Quiet and carefully composed in public. Mary has learned to make herself small, to smile and nod and never cause waves. She's the picture of the "good daughter" on the surface, polite, studious, helpful. There's a sharpness to her when she lets her guard down, a dry wit and quiet defiance that only comes out in safe spaces. Mother resents her.
