Guy Gavriel Kay has a unique approach to ‘fantasy.’ Take two parts historical fiction, one part mythology, one part magic, stir and serve over a piping hot revolution. I read Kay’s Sarantine Mosaic for the Cannonball last year, and from the very start of Under Heaven, it’s obvious that the two works grew out of the same place. They are both, at their core, stories about empires and the surprising ways that ordinary citizens can change the course of history. Where Sailing to Sarantium looked at the glories of Byzantium and Christian Rome, Under Heaven explores Tang Dynasty China, and more specifically, the period of history known as the An Shi Rebellions. However, Kay may have followed these events too closely to have crafted a really good story.
