The Black Cloud

Rating:
Summary: Good early '60s hard sf
Review: This was one of the first sf novels that I ever read, when I was about 12 years old. So I have a soft spot for it. Interesting premise--an instellar "black cloud" (that for all it knows thinks it might be immortal) shows up and covers the Earth. This is not such a good thing. Some scientists attempt to contact it, with some good--and some bad--results. Good early '60s, by the man who first suggested the "steady-state" theory of the universe.
