"I'm going to tell you the things that only a big brother will tell you; that your father will never say". A millennial text that echoes Sex and the City, Girls or Fleabag, Ethics for Julia steers well clear of approved protocols and bases itself purely on the disarming sincerity of what it wants to say. Backed up with references from philosophy and popular culture, the author combines confessional narrative and graphic humour with a personal 25-year-old perspective to educate his sister of 14 on the dangers and joys of physical and spiritual love, normalising the communication about sex between adults and children in the age of Tinder, Grindr and online board games.
