In speculative fiction, tea has appeared as an important cultural fixture most often in fantasy, but a number of science fiction stories have featured the drink. This includes C.J. Cherryh’s Foreigner books, Aliette de Bodard’s Xuya Universe tales (particularly the tellingly named The Tea Master and the Detective) and Becky Chambers’ recent Monk & Robot series. 

The book that first comes to my mind, however, is Ann Leckie’s Ancillary Justice, first in her ongoing Imperial Radch series. In the domineering empire of the Radch, tea and its attendant rituals are luxuries for humans—nonhumans bound in service to the empire, like the “corpse soldier” main character, Breq, must make do with water. (Or fish sauce.) Beyond tea, I have always been interested in exploring social and political domination, and Leckie’s thoughtful, culturally vivid first novel has been a major influence on my work, especially my own debut novel.
