To potential members, the Science Fiction Book Club offers an extensive selection of fiction (and some non-fiction) spanning every possible sub-genre from this hugely popular literary direction: alien worlds, alternate history, time travel, space adventure, near future, first contact... the list goes on. Fans of witches, dragons, vampires, elves and other supernatural beings will be at home at SFBC too: from contemporary fantasy via mythology and folklore to supernatural romance, SF Book Club has it all covered.
If you are into mainstream bestsellers, you need look no further: Sci-Fi Book Club features all the mega-popular authors which include sci-fi and fantastic elements in their work, such as Stephen King, Dean Koontz, Stephenie Meyer, James Patterson... to name just a few.
True SF fans, however, will probably be much more interested in names that are not as widely recognizable in the general public's eye, but are well known and highly regarded within the genre: Terry Brooks and his Shannara series of novels; Laurell K. Hamilton, best known for her Anita Blake series, published in comic book/graphic novel form; the indestructible Ann McCaffrey, who had been writing SF novels and winning awards well before the majority of the club's current membership body was even born; Terry Pratchett, UK's best selling author of the 1990's, best known for his popular and long-running Discworld series of comic fantasy novels; Orson Scott Card, the only author to win both of science fiction's top prizes (the Hugo Award and the Nebula Award) in consecutive years, with his novel Ender's Game and its sequel Speaker for the Dead; and many others, too many to list them all.
Classic SF and fantasy authors aren't neglected either: George Orwell, Arthur C. Clarke, J.R.R. Tolkien, Robert A. Heinlein, Isaac Asimov, Marion Zimmer Bradley, Ray Bradbury... they are all featured with reprints of their best work, often in the shape of an omnibus edition – a rather popular means of delivering the goods within the Sci-Fi Book Club.
Talking about classics without mentioning such influential series as Star Wars and Star Trek would be, well, unfair. Star Wars: The Legacy of the Force is a series of 9 novels set in the Star Wars fictional universe some three decades after the conclusion of events in the last movie (Return of the Jedi). If you'd like to know what happened with Luke Skywalker and the gang afterwards, you can't miss this series. Star Trek is a series of books based on the popular TV series; most of the books were (co)written by William Shatner, the popular captain Kirk, himself.
Comics and graphic novels are another area where Sci-Fi Book Club offers a decent selection. Batman, X-men, Conan, Buffy the Vampire Slayer, Hellboy... Ever wonder how would Superman, Batman and Wonder Woman get along? Now's your chance to find out.
Finally, non-fiction: it is not a very populated category within SF Book Club, but the few items present still deserve some attention. Reference books are the most common subject here and they can be about anything: a popular SF/Fantasy TV or comic book series, for example, where you can find all about the main characters, the timeline of events etc -- but on occasion you can also find references on vampires, fairies and similar otherworldly creatures.
It should also be noted that as an SFBC member you will have access to all the books from other Booksonline book clubs -- such as The Literary Guild Book Club (bestsellers) or History Book Club -- so if you want to buy something outside the sci-fi genre, chances are you won't have to look any further.
