“But you must not change one thing, one pebble, one grain of sand, until you know what good and evil will follow on that act. The world is in balance, in Equilibrium. A wizard's power of Changing and Summoning can shake the balance of the world. It is dangerous, that power...It must follow knowledge, and serve need.”

American author

Ursula K. Le Guin was an American author, active from the late 1950s into the early twenty-first century. She is best known for speculative fiction, especially the science fiction set in her Hainish universe and the fantasy series Earthsea. Her first work appeared in 1959, and her career lasted nearly sixty years. Over that time she wrote more than twenty novels and more than a hundred short stories, along with poetry, literary criticism, translations, and children's books. Although she was often described as a science fiction writer, she said she would rather be known as an American novelist.
