This exceptional young adult/crossover debut is the compelling, sharply observed story of a family in crisis told, in an understated narrative voice reminiscent of Mark Haddon or Harper Lee, by 13-year-old Lou, who is on the autism spectrum. This bright teenager, the object of violent attention at school and some selfish neglect at home, chronicles the revelation of her teacher father’s affair with a sixth former and her mother’s psychotic episode.
