What if? That simple question drives the best science fiction books. They explore technology, society and the future, often with surprising accuracy. Orwell's dystopias and more await in modern fiction; for the real science, see popular science.
Many science fiction ideas have already come true, and the best of these novels ask what technology does to people, not just what it can do.
The best way to find a novel you love is to follow your mood. Read the first few pages, trust your instinct, and never feel guilty about setting aside a book that does not grab you.
