Science fiction makes you think.

Although sci-fi pushes past the boundaries of reality, it paradoxically allows readers to think about questions that hit closest to home. 

Technology, society, war, existence, family — these main sci-fi themes are things that we all deal with every day.

No literary list is exhaustive, but we've put together a list of 17 that any real sci-fi fan should definitely read.
