Andy Weir and Ernest Cline.
Andy Weir wrote a piece of fanfic called Lacero for Ready Player One!! That’s right, but the best part is that it became Canon. Here is Andy sharing his fame on Facebook. (My favorite part is the ‘booyah’ part. 🙂 )
Because it is just plain cool. The ending took me by surprise and puts a cool twist on the plot. If you are a fan of Ready Player One then by all means go read the short story Lacero on Andy’s blog.
