I finished reading A Wizard of Earthsea a couple days ago, and have started the second book in the Earthsea trilogy, the Tombs of Atuan. Holy crap, that book was good. Like, I know the Earthsea books are one of the great classic fantasy series, but I have so far not been super-impressed with the other classics. I think I tend to come at them with the wrong frame of mind. Mainly, it's that they're built on the earliest sparks of tropes that have, by the time I reach them, had decades to get old and played-out.
But the Earthsea books don't have that problem! Part of it, certainly, is that island worlds have not become a trope played out to the point of inducing groans. Earthsea is unique in a way that some of the other SF/F classic settings (Middle Earth, the sprawl, Mars...) just aren't. And part of it is that Le Guin is a freaking genius, and fully explores the implications of a lot of cool things that other writers might just have thrown in, leaving them open to future deconstruction.
I've gotten more than halfway through the Tombs of Atuan already, and it may not make it through my next shift at work. I'm not sure whether to bring The Farthest Shore, too. Either way, I highly recommend them.
