The Gods Themselves
A wonderful book by my most favourite Sci-Fi author, Isaac Asimov. Remeber the law of conservation of energy/momentum/angular momentum? No?! then this is not the book for you. This is a wonderful book but, it's slightly high on science. It's mainly about a freshly invented means of inter universe energy transfer which could potentially play havoc by blowing up the sun and hence, resulting in the destruction of our universe. The first edition of the book was published in 1972, just 3 years after man successfully landed on the moon. Asimov's ingenuity is strikingly visible in the book when he speaks of under ground Lunar colonies and the effects of residing on the moon over generations of human beings. But, somehow it was not as much a page turner as the 'Nightfall' or for that matter, 'Nemesis'. But, this is totally worth reading if you are a hard core Sci-Fi buff, after all, the book's got Asimov a Hugo award.
