The World of Ice and Fire: The Official History of Westeros and The World of A Game of Thrones

The World of Ice and Fire: The Official History of Westeros and The World of A Game of Thrones - George R.R. Martin, Linda Antonsson, Elio M. Garcia jr. Although I have yet to read the book cover-to-cover, I have skimmed the whole book and read some of the more recent history and I find it absolutely thrilling. To top it all off the maps and artwork is stunning. A must read for all Game of Thrones fans.
