"Game of Thrones versus History: Written in Blood is a collection of thought-provoking essays by medieval historians who explore how the enormously popular HBO series and fantasy literature of George R. R. Martin are both informed by and differ significantly from real historical figures, events, beliefs, and practices of the medieval world. From a variety of perspectives, the authors delve into Martin's plots, characterizations, and settings, offering insights into whether his creations are historical possibilities or pure flights of fantasy."
