Enjoy the best in free Science Fiction.

Science fiction books are an amazing way to escape into the future or to a distant planet with advanced alien civilisations and technology only limited by the imagination of the author. Some books will take a very scientific approach to what could really be possible in the future whilst others may be more loose with their application of science as we know it today. Whatever the case, it makes for some awesome storylines.

With science fiction novels you will be taken to a place where science has advanced or is different to what we know today. In this backdrop there might be stories of adventure or war or discovering new planets and new species. Maybe humans have colonised Mars and are fighting an evil alien race or the hero has to negotiate the politics of a world 1000 years in the future from now. Maybe the machines have taken over and enslaved humanity and the last free people have to fight for the survival of the human race.

The science fiction genre has been popular since the late 19th century when authors like Jules Verne (From the Earth to the Moon) and H. G. Wells (War of the Worlds) published science fiction works that have become classics. There novels grabbed the attention of the nations as new and strange ideas were put down on paper.

In the early 20th century science fiction short stories became popular in the USA due to the publishing of pulp magazines (magazine collections of short stories). These would keep teenagers enthralled with amazing tales of the future and alien worlds.

Later in the 20th century writers like Isaac Asimov and Arthur C Clark emerged with more science based novels. Isaac Asimov wrote many science fiction novels and hundreds of science fiction short stories. His Robot series contained the three laws of robotics which are used in the real world today.

Arthur C Clark is best known for his 2001: A Space Odyssey and the subsequent novels. Some of the science predicted in these novels came true decades after they were written and the author took great effort to base his predictions on real science.

Science fiction has become so popular in TV and cinema today that this has the knock on effect of popularizing the overall genre. Today there are huge selections of science fiction books and our real world technologies fuel the ideas for what a future may hold. It is a massive genre that continues to grow and grow.

Science fiction used to be the domain of nerds but not anymore – its very cool to be a fan of science fiction books. It is great way to escape daily life and provoke thinking about how a future could look.
