This seems to be basically out of print, and that makes me sad. Written by the creator of the Prince of Persia videogame, and inspired by the true story of the fall of the Knights Templar, this seems like an HBO executive's dream; historical setting when violence and sex were commonplace, love triangle, religion vs politics, treasure heist, secretive order, strong females. Very fitting that the GoT showrunners have a blurb on the cover. Excellent!
