Although the book contains no confirmed sexual assault, it is theorized that the main child protagonist may have experienced sexual abuse at the hands of his father. There are subtle references to this in the book and his possible abuse, although not specifically defined as sexual, is a plot point throughout the book. There is a scene where the above-mentioned abusive father starts initiating sex with his wife while she is trying to have a serious conversation. She does not appear to be bothered by this.
