Across two parallel narratives, Murakami draws readers into a mind-bending universe in which Lauren Bacall, Bob Dylan, a split-brained data processor, a deranged scientist, his shockingly undemure granddaughter, and various thugs, librarians, and subterranean monsters collide to dazzling effect. What emerges is a novel that is at once a hilariously funny and a deeply serious meditation on the nature and uses of the mind. This unabridged edition uses the original Japanese title of the book, which was later inverted for foreign publications.
