On Growth and Form
by D'Arcy Wentworth Thompson

Raphaël de Valentin, a penniless young man on the edge of death, wanders into a Paris curiosity shop and leaves with a scrap of wild-ass skin that grants any wish its owner speaks aloud. The catch is fatal: with every desire fulfilled the skin contracts, and so does the span of his own life. Balzac turns this bargain into a meditation on how longing consumes us, weighing raw appetite against the plain will to endure. Salons, gambling dens, and a doomed love affair carry Raphaël toward the limit he keeps trying to outrun. One of the cornerstones of the Comédie humaine, it fuses fable with social realism.
