Central China, 1264. When Mongol armies storm into the Middle Kingdom, the descendents of Yun Cai (Taming Poison Dragons) are trapped in a desperate siege that will determine the fate of the Empire. Guang and Shih are identical twins, one a heroic soldier idolised by the city he defends, the other a humble doctor. In the midst of war, jealous conflicts over Shih's wife and concubine threaten to tear the brothers apart. Enemies close in on every side - some disturbingly close to home. Can the Yun family survive imprisonment, ruthless treachery and Kublai Khan's bloody hordes? Or will their own reckless passions destroy them first? Breaking Bamboo is the second installment of a trilogy set in Song and Yuan Dynasty China, charting the trials and adventures of the Yun clan.
