I am currently reading the final book of The Three Body Problem trilogy - Death's End. Sounds gloomy? It's not; it's inspiring.The whole trilogy is captivating, genuine science fiction. Brief summary (slight spoiler): an alien civilization (Trisolaris - the three suns of the title) is discovered four light years away. They are struggling with constant sequences of planetary destruction and reconstruction, as a result of being "thrown" between the three suns, and will eventually be subsumed into one of the suns. Once they get 'pinged' by an Earth signal, they figure out it might be a nice place to settle so they send an invasion fleet, which will arrive on Earth in 400 years. There is a lot of astrophysical text ("hard science fiction") and we follow (sometimes changing times forwards and backwards) Earth's scientific development and the scientists involved.
One of the my best reads in a long time. It's a fascinating study of how humanity deals with an alien threat and how it evolves as a result. Written by Liu Cixin and translated by Ken Liu and Joel Martinsen, the books have won many awards.
Next will be Freakonomics: A Rogue Economist Explores the Hidden Side of Everything by Steven Levitt and Stephen Dubner.
To be followed by Claire Tomalin's biography of Samuel Pepys "The Unequalled Self".
