As quoted by Simon: Ex Libris is a novel with twelve chapters that can be shuffled into any order yet will always present as a cohesive story arc. The project aims to make a print run where each individual copy contains chapters that have been arranged at random. With nearly half a billion possible combinations, each copy will be one of a kind yet all of them will tell the same story.
Simon is one of the most innovative and intelligent writers I know. Please consider supporting this special project in storttelling.
