The Green Glass Sea

Dewey is expecting her father to come from Chicago to pick her up. Instead, a woman in a green army uniform arrives, tells her he's "somewhere in New Mexico," and drops her off at the train station all alone. After a long trip, Dewey finds herself in Los Alamos, a community of scientists that doesn't officially exist. While the adults work day and night on something called "the gadget," the kids have lots of unsupervised time-as long as they don't go past the armed guards and wire fences. Winner of the 2007 Scott O'Dell Award and the 2007 Judy Lopez Award.
