<div class="synopsis">
<p>Years after a rebellion spurred by a stolen bride to be and the blind ambitions of a mad king, Robert of the house Baratheon sits on 
the much desired Iron Throne. In the mythical land of Westeros, nine noble families fight for every inch of control and every drop 
of power. The King's Hand, Jon Arryn, is dead. And Robert seeks out his only other ally in all of Westeros, his childhood friend 
Eddard Stark. The solemn and honorable Warden of the North is tasked to depart his frozen sanctuary and join the King in the 
capital of King's Landing to help the now overweight and drunk Robert rule. However, a letter in the dead of night informs Ned 
that the former Hand was murdered, and that Robert will be next. So noble Ned goes against his better desires in an attempt to 
save his friend and the kingdoms. But political intrigue, plots, murders, and sexual desires lead to a secret that could tear the 
Seven Kingdoms apart. And soon Eddard will find out what happens when you play the Game of Thrones.</p>
