The Tombs of Atuan (Earthsea Cycle, #2)
Had a really hard time getting into this, but it had me by the end. Liked it much better than A Wizard of Earthsea. That one was too scattered for me, but once I got past my initial aversion with this one (a lot of it probably left over from reading the first one), I got caught up in the story of Arha/Tenar, the young girl who has everything taken from her, and then fights to find herself again.
I think the difference is that Tombs of Atuan had a physical focus that A Wizard of Earthsea lacked. Ged wandered all over creation, and the focus was always on where he was going and what he was doing, rather than his inner life as a character. Actually, I take that back sort of. All those travels were about his inner life, but it was like his inner life was plastered metaphorically all over Earthsea, and we were supposed to infer what was going on inside of him by what was happening outside. With Tenar, Le Guin had no choice (or rather, she'd painted herself into a corner by creating her that way) but to spend lots of time on Tenar's thoughts. Tenar doesn't travel the world, only explores the dark crevices of the place where she lives, and spending her life in such darkness, Le Guin must have been compelled to flesh her out a bit more. Also enjoyed Ged more in this one, because he was a familiar presence, and because I was seeing him through Tenar's eyes, which made him more emotionally interesting.
I hope numbers three and four are more like this one then they are A Wizard of Earthsea.
