The Woman Who Died a Lot / Jasper Fforde

The Wingco's research work involved finding some evidence of the disputed Dark Reading Matter. Theoretical storyologists had calculated that the readable BookWorld makes up for only 22 percent of visible reading matter — the remainder is thought to be the unobservable remnants of long-lost books, forgotten oral tradition and ideas locked in writers' heads when they died. A way to enter the Dark Reading Matter was keenly sought, as it might offer a vast amount of new ideas, plots and characters as well as a better understanding of the very nature of human imagination, and perhaps even why story exists at all.
