When “A Wrinkle in Time” came out in 1962, girls mostly didn’t read science fiction – and it wasn’t written for them. But L’Engle’s first book defied the norms. “Though a major crossover success with boys as well (with more than 10 million copies sold to date), the book has especially won over young girls. And it usually reaches them at a particularly pivotal moment of pre-adolescence when they are actively seeking to define themselves, their ambitions and place in the world.”
