In this essay I want to explore family in science fiction through the lenses of Octavia Butler, Charlie Jane Anders, Starhawk, John Scalzi, and Martha Wells. Be forewarned that there are spoilers for the following books: the Xenogenesis series by Octavia Butler, Victories Greater Than Death by Charlie Jane Anders, The Fifth Sacred Thing by Starhawk, The Old Man’s War series by John Scalzi (specifically, Old Man’s War, The Ghost Brigades, The Sagan Diary, The Last Colony, and Zoe’s tale), and the Murderbot series by Martha Wells. These books all have a very different view as to what family means and also, in some ways, a really similar one.
