Everything I Never Told You by Celeste Ng,

Everything I Never Told You:
Lydia is the favourite child of Marilyn and James Lee; a girl who inherited her mother’s bright blue eyes and her father’s jet-black hair. Her parents are determined that Lydia will fulfill the dreams they were unable to pursue – in Marilyn’s case that her daughter become a doctor rather than a homemaker, in James’s case that Lydia be popular at school, a girl with a busy social life and the centre of every party.
