Im up to the fourth book in the Earthsea cycle; the pleasure comes from the reading, which is dark, and visual, and compelling. However, in reading each of the first three I realized that I had read them before, apparently long enough ago to not remember What Happens Next but still, as it happens, I think, ah, I remember this...the fourth book so far hasn't given me any deja vu moments, so I'm cool with that.
The pain comes from having bought the entire set (two at a used book table and two in the bookstore at full price), apparently, again. The fourth book wasn't published until 1990, and that may explain why I've not read it. Thank heaven for small favors.
