One of the most successful series of fantasy novel sin recent years is George R.R. Martinโs, A Song of Ice and Fire, which is essentially a sprawling re-imagination of Englandโs War of the Roses, in a world called Westeros where dragons once lived, where dark magic dwells in the shadows, and where the dead walk again. HBO adapted the novels an even more successful television series, A Game of Thrones, and as the sixth season approaches, there is a saying that hovers over the entire plot, the characters that drive it, and the world they inhabit:
Winter is coming.
