In "The Book of Sand" by Jorge Luis Borges, the protagonist encounters a mysterious man selling an infinite book known as the Book of Sand. The conflict arises when the protagonist becomes obsessed with the book's endless pages and loses himself in its vastness. Unable to find any order or sense in the book, he tries to escape its grasp but fails. The conflict primarily lies within the protagonist's struggle to understand and control the Book of Sand, which ultimately leads to his descent into madness and his desperate attempts to be rid of it.
