Irene must journey through a horrid snowstorm to deliver a package to the duchess. Inside the package is a beautiful ball gown made by her seamstress mother who has fallen ill for the day. Despite her mother's protest, Irene is determined to brave the snow to reach the palace in time, so the duchess can wear her mother's gown to the ball.
(Fun find: As I was looking up Brave Irene, I came across other books by William Steig, and I learned the movie Shrek is based on one of his picture books! Who knew!)
