Synopsis: "Deep inside a mountain in what used to be North America dwells the last of humanity. Welcome to the Biodome, where steel, rock and armed guards separate the privileged from the slaves. Born and raised a slave in the Pit, Sunny O'Donnell has always accepted that she'll spend her life working to keep the Dome running and, if she lives long enough, willingly meet her end in the annual Cull when she reaches the age of thirty-five. This was the price her ancestors paid for their place inside the Biodome, the only safe haven from the global nuclear war of 2024. But when Sunny's mother is killed in the Cull, the hopeless reality of her future becomes painfully clear. Bereft and disillusioned, she heads down a reckless path that sets off a deadly riot in the Pit and leaves her accused of treason. Her only way of escaping public execution is to make a truce with her prison mate, who happens to be the heir to the dictatorship and hated enemy of the Pit. Now caught between two worlds on the brink of war, Sunny must weigh her own survival against risking everything to save the Pit." (source: Amazon.com)
