The story begins with a vacuum cleaner. And a squirrel. Or, to be more precise, a squirrel who gets sucked into a Ulysses Super Suction wielded by Flora’s neighbor, Mrs. Tickham. The rather hairless squirrel that is spit out is not the same one that went in. That squirrel had only one thought: I’m hungry. After Flora performs CPR, the rescued squirrel, newly named Ulysses, is still hungry, but now he has many thoughts in his head. Foremost is his consideration of Flora’s suggestion that perhaps he is a superhero like The Amazing Incandesto, whose comic-book adventures Flora read with her father.
