Struggling to fit in at his new school after being expelled for his treatment of Auggie Pullman, Julian is visited by his grandmother and is transformed by the story of her attempts to escape Nazi-occupied France during World War II.

In R. J. Palacio's bestselling collection of stories Auggie and Me, which expands on characters in Wonder, readers were introduced to Julian's grandmother, Grandmère. Here, Palacio makes her graphic novel debut with Grandmère's heartrending story: how she, a young Jewish girl, was hidden by a family in a Nazi-occupied French village during World War II; how the boy she and her classmates once shunned became her savior and best friend.
