Compound

Eli and his family have lived in the underground Compound for six years. The world they knew is gone, and they've become accustomed to their new life. Accustomed, but not happy. No amount of luxury can stifle the dull routine of living in the same place, with only his two sisters, only his father and mother, doing the same thing day after day after day. As problems with their carefully planned existence threaten to destroy their sanctuary―and their sanity―Eli can't help but wonder if he'd rather take his chances outside. Eli's father built the Compound to keep them safe. But are they safe―really?

The Compound is a 2009 Bank Street - Best Children's Book of the Year.
