Mine is in the Earthsea books by Ursula K. LeGuin. I like it because magic isn’t free. It’s important, a part of nature, must be used sparingly so the world stays in balance. There are consequences to misuse & overuse. It’s not like Harry Potter where magic is used frequently for trivial reasons.

Earthsea does magic SO well. I love the way LeGuin shows how dangerous it is to alter things and interfere with the world, and that the cost if you use it wrong, can haunt you for your entire life.
