They’re just a few words on books. But what are blurbs really doing (other than trying to twist your arm)? This book is all about those 100-or-so words that take seconds to read but can make a world of difference – and what they tell us about literary history, the art of writing, authors from George Orwell to Zadie Smith, genres from children’s fiction to bonkbusters, cover design, the dark arts of persuasion and even who we are as readers. It’s also about quotes, titles, first lines, hooks, adverts, puns, swearing, plots, someone called Belinda and much more. It answers questions such as: Why do some authors hate blurbs so much they burn their own books? Should all adjectives be murdered? Is it true that (checks jacket) you need an animal on a book’s cover to make it a bestseller?
