The first thing Henry and Zelda want you to know about Miss Applebaum is that she's full of surprises, like bringing a dead cat to school in a Bloomingdale's box and making her students dissect it.

Henry and Zelda have known each other forever, but they couldn't be more different. While Zelda walks down the street admiring the sky, Henry's eyes are glued to the gutter, looking out for loose change. When they learn their beloved Miss Applebaum is dying of cancer, they have very different reactions, but they're sure of one thing. However much time Miss Applebaum has left, they will do everything they can to make sure it's spectacular.
