I read one of Larry Niven's books recently (published in 1985). "Lucifer's Hammer". It was slow at first, I was doubting it would be very good, but after the comet hit early on in the book, it really picked up into a first rate book after that. It might have even been recommended to me by someone here at ETS. I know in the past I have asked for book recommendations, or maybe it was somebody else's thread that I just participated in. Can't remember. But I've picked up several good book suggestions from folks here.
