If you're a fantasy junkie and/or an HBO subscriber, odds are pretty good that you've been eagerly awaiting the return of the hit series A Game of Thrones. It's a serial adaptation of George R.R. Martin's A Song of Ice and Fire novels, and HBO's second season of the show begins on Sunday night. If you haven't read the books (or even if you have) you're probably a little lost when it comes to the expansive geography of the novels. Never fear, viewers: the Westeros Map app from developer Sergey Rekuz is here to help.
