My Superpower is a regular guest column on the Skiffy and Fanty blog where authors and creators tell us about one weird skill, neat trick, highly specialized cybernetic upgrade, or other superpower they have, and how it helped (or hindered!) their creative process as they built their project. Today we welcome Ken Liu to talk about how the power of tax enthusiasm relates to Grace of Kings. My superpower is the ability to get readers excited about taxes. Taxes are critical in my silkpunk epic fantasy, The Grace of Kings. This is the story of two unlikely friends, a duke and a bandit, who join together to overthrow tyranny only to find themselves on opposite sides of a deadly rivalry over how to create a more just society. There are all sorts of cool things in it:  soaring battle kites and airships based on Chinese prototypes from antiquity; unyielding heroes, kennings, and litotes in the mode of Anglo-Saxon epics; magical books that read minds; jealous gods who are concerned with the value of Pi; a street urchin who becomes the greatest battlefield tactician of her generation and teaches women to fight in the skies; ladies and princesses who plot and fight alongside lords and princes; and giant water beasts who bring storms and tempests to human affairs.
