From commuters absorbed by Harry Potter books to the wide appeal of JRR Tolkien's The Hobbit, the mystery of why some grown-ups like reading children's books may finally be solved. Adults are hacked off with the disappointment of modern life.
Dr Louise Joy, a Cambridge University academic, believes classic children's books, and the work they inspire, attract older readers because they give them things they cannot find in their everyday lives, including direct communication, tasty home-cooked food, and tolerance towards eccentricity.
The researcher claims such books represent a "symbolic retreat from the disappointment of reality".
"Books such as Lewis Carroll's Alice in Wonderland and Roald Dahl's James and the Giant Peach offer a world where self-consciousness is overthrown and relationships are straightforward," says Dr Joy.
"But relationships in the real adult world are often fraught by miscommunication and the impossibility of understanding one another properly."
