After I got through with animal stories and tramp steamer adventures as a kid, I moved into sci fi and fantasy, and stayed there for something like thirty years. It’s an incredibly rich, thought-provoking vein of reading pleasure. And if you haven’t dipped into it, there’s no time like the present.
Wired just published a great list of sci fi and fantasy classics that will get any new fan started—books and movies both. There are classic novels like Dune, The Left Hand of Darkness, and The Foundation Trilogy, and newer faves such as Neal Stephenson, Hugh Howey, and J.K. Rowling. Movies/TV shows include Blade Runner, Alien, Total Recall, Dark City, and Firefly. There are some authors new to me, too, that I’ll have to check out, including Lev Grossman, Ernest Cline, and Ann Leckie.
