Audrey Niffenegger said this quote

“ When I began writing The Night Bookmobile, it was a story about a woman's secret life as a reader. As I worked it also became a story about the claims that books place on their readers, the imbalance between our inner and outer lives, a cautionary tale of the seductions of the written word. It became a vision of the afterlife as a library, of heaven as a funky old camper filled with everything you've ever read. What is this heaven? What is it we desire from the hours, weeks, lifetimes we devote to books? What would you sacrifice to sit in that comfy chair with perfect light for an afternoon in eternity, reading the perfect book, forever? ”
