For the millions of readers who loved J. R. Palacio's Wonder, Julian was the biggest bully in Auggie Pullman's class. In White Bird, another side of Julian is revealed as he learns the touching and powerful story of his grandmother, who, as a young Jewish girl, hid from the Nazis in occupied France during World War II. As Grandmère tells Julian, "It always takes courage to be kind. In those days, though, such kindness could cost you everything."

The book includes an afterword by award-winning author and critic Ruth Franklin, as well as extensive information for readers who want to learn more about that historical period.
