I just finished it a few weeks ago for Decolonizing Africa class, and loved it. Of course, it helped that our Professor walked us through the book, and explained the differences between Western storytelling, and traditional Igbo story telling, as well as pointed out some of the more subtle themes and references, that I honestly missed the first time through. Liek when Okonkwo hands his daughter a piece of fish while he's eating---I didn't realize that he meant he considered her to be a son. Things like that.

Achebe's book Anthills of the Savannah is also pretty good--well, the first 48 pages are pretty good. I haven't gotten much past that.
