It is a brilliant story of a team of scientists, and their
governments, trying to deal with a threat to life on earth. It is
not depressing or dramatic however and Hoyle manages to fit in alot of theory and scientific explanations, a social/political critique and some endearing and likeable characters. It is truly original and leaves you buzzing.
I really don't want to ruin it for anyone who decides to read it and so feel I can't say much more - other than I urge you to read it!
Next is Franz Kafka's Metamorphosis and Other Stories, not a fan..
