I've read the entire "Dance to the music of time" sequence, if you read one you need the rest for the whole life of the characters. I'm in the same position with C.P. Snow's "Strangers and brothers", about three quarters of the way through that.

It's been thirty years since I read Chinua Achebe's "Things fall apart" so I don't know if I would still think it a good read, but I enjoyed his "Anthills of the savanna" more recently.
