The story is about a father and daughter spending a special morning together. The father has been off fighting WWII for most of the daughter's life, so they're getting to know each other. Liz seems to be nine or ten years old. It's based on Lois Lowry's own life; there's even a picture of her as a child on the final page.
Lowry's writing is great as always, there are excellent details like the shirt and the pie, but the brown- and gray-toned illustrations didn't thrill me.
Add this to the list of picture books that are well-done, but may miss their audience because kids of the right age are all stuck on chapter books.
