From revered early authors, to modern masters, from hard to "soft" science, from foundational texts to contemporary classics, and everything in between, this list has it covered. A few notes on composition before diving in. This list is divided into ten sections, with five entries for each. Yet there is plenty of overlap between these categories. A cyberpunk novel might also qualify as dystopian fiction. A title readers expect to find filed under "classics" might instea be in the "First Contact" or "AI" category. And in order to capture as much of the scope of the genre, and include as many authors as possible, only one book per writer has been included on this list. This will certainly spark debate among hardcore sci-fi heads, but for newbies to the genre, think of it as a general introduction. If an author made the cut here, it is absolutely worth checking out the rest of their work, and then coming back to share an informed opinion about which book should be here.
