It is 1946, and the events of The Green Glass Sea have changed the world?and Dewey Kerrigan?s life. She?s now living near the White Sands Missile Range in New Mexico with the Gordon family. Dr. Gordon is working on rockets that will someday go to the moon; Mrs. Gordon is working on stopping the Bomb. Meanwhile, Dewey and her ?sister,? Suze, share secrets, art, and science as they adjust to high school in an isolated desert town. Then, like a different kind of dropped bomb, Dewey?s long-lost mother, Rita Gallucci, reappears in their lives. And she wants to take her daughter away.
