The Wall - reading

Finished "The Wall" by Jeff Long. First of all, there are too many books out there named, "The Wall." And no, this has nothing to do with Pink Floyd. It's about a rock climber's midlife reliving of past glory on El Cap in Yosemite, and how his life is tangled up with several others. Had I any knowledge of rock climbing terminology and culture, I would have probably liked it even more, but even without that, I liked it well enough. However, I didn't like the ending. That makes it difficult to say what I didn't like without spoilers. The revealation was fine, but where it went from there just annoyed me. I felt shorted. For the most part, the writing was clean and the descriptions and analogies painted the scenes nicely.
