/lit/ - Literature

Currently reading The Colour of magic, and I dont know if I missed something, but I dont get how the day/night cicle works, does the sun orbit around the rims of the disc or does it go all the way circling the turtle like it would do if the world where round?

besides that, I like the humor, the same way I appreciated the humor in the hitchkhiker series, I like it, but I never found anything that I considered laugh-out-loud funny, maybe im just dead inside.
