Audrey Niffenegger's two novels, ''The Time Traveler's Wife'' and ''Her Fearful Symmetry'', have made her one of the most popular writers in the world. She is also the author of two extraordinary novels-in-pictures, ''The Three Incestuous Sisters'' and ''The Adventuress''. Now, with ''The Night Bookmobile'', she has written her first graphic novel. First serialised in the ''Guardian'', ''The Night Bookmobile'' tells the story of a young woman who one night encounters a mysterious disappearing mobile library that happens to stock every book she has ever read. Seeing her history and her most intimate self in this library, she embarks on a search for the bookmobile. Over time, her search turns into an obsession as she longs to be reunited with her own collection and her memories.
