So I promise now that the newspaper and this website will not be reviewing any book which is explicitly aimed at just girls, or just boys. Nor will The Independent’s books section. And nor will the children’s books blog at Independent.co.uk. Any Girls’ Book of Boring Princesses that crosses my desk will go straight into the recycling pile along with every Great Big Book of Snot for Boys. If you are a publisher with enough faith in your new book that you think it will appeal to all children, we’ll be very happy to hear from you. But the next Harry Potter or Katniss Everdeen will not come in glittery pink covers. So we’d thank you not to send us such books at all.
