Expanded rules are as follows:
To take part this challenge, pick a start date and start a discussion thread with your name and the date in the title. That thread is your personal tracking thread. Throughout the year, keep that thread updated with start and finish dates of the novels you use to fill out the categories. You may also include notes and reviews in that thread, so others can get ideas for what to read in their challenges.
For books to qualify in any category, they must be at least 100 pages long. A maximum of five books may double-qualify (that is, count in two categories), and no book may qualify for more than two categories. This ensures that if you complete the challenge you will have read a minimum of 35 books.
Feel free to add books you've read for this challenge to the shelf. You may also add books you've listed in the suggestion discussion thread. Please DO NOT add books to the group shelf unless they fall into one of those categories; I want it to remain browseable for everyone in the group.
The following subgenre definitions should be followed:
Hard SF: Characterized by rigorous attention to accurate detail in quantitative sciences, especially physics, astrophysics, and chemistry, or accurately depicting worlds that more advanced technology may make possible.
Soft or Social SF: Works based on social sciences such as psychology, economics, political science, sociology, and anthropology. May also describe works focused primarily on character and emotion.
Cyberpunk: Works in which the time frame is usually near-future and the settings are often dystopian. Common themes include advances in information technology and especially the Internet, artificial intelligence and prosthetics, and post-democratic societal control where corporations have more influence than governments. Nihilism, post-modernism, and film noir techniques are common elements, and the protagonists may be disaffected or reluctant anti-heroes.
Alternate History: Works based on the premise that known historical events turned out differently. May or may not include time travel.
Military SF: Works set in the context of conflict between national, interplanetary, or interstellar armed forces; the primary viewpoint characters are usually soldiers. Stories include detail about military technology, procedure, ritual, and history; military stories may use parallels with historical conflicts.
Superhuman: Works that deal with the emergence of humans who have abilities beyond the norm. This can stem either from natural causes or be the result of intentional augmentation. These stories usually focus on the alienation that these beings feel as well as society's reaction to them.
Apocalyptic/Post-Apocalyptic: Works concerned with the end of civilization through war, pandemic, astronomic impact, ecological disaster, or mankind's self-destruction.
Space Opera: Works that emphasize romantic, often melodramatic adventure, set mainly or entirely in space, generally involving conflict between opponents possessing powerful (and sometimes quite fanciful) technologies and abilities. Perhaps the most significant trait of space opera is that settings, characters, battles, powers, and themes tend to be very large-scale. These stories typically follow the Homeric tradition, in which a small band of adventurers are cast against larger-than-life backdrops of powerful warring factions.
Steampunk: Works set in an era or world where steam power is still widely used—usually the 19th century, and often set in Victorian era England—but with prominent elements of either science fiction or fantasy, such as fictional technological inventions like those found in the works of H.G. Wells and Jules Verne (but not actually by authors of that era) or real technological developments like the computer occurring at an earlier date.
Feminist SF: Works which pose questions about social issues such as how society constructs gender roles, the role reproduction plays in defining gender and the unequal political and personal power of men and women.
Science Fiction masquerading as Fantasy: Works featuring traditional fantasy elements such as iron-age of technology/knowledge or magic, but which reveal a traditional science fiction explanation such an apocalypse or a disintegration of communication with other human planets.
