In the late nineteenth century, in Washington Square, two children play with a red balloon… and so begins the strange romance between Daniel, beautiful and tiny, and Grace, known as The Fat Princess, an orphaned girl whose enormous girth matches her wealth. Each wishes for a life of the mind, for artistic mastery, to be read and to be understood — most of all by each other — but through their lives, the couple only occasionally meet, until Daniel uncovers Grace’s great secret in her House of Death.
