Across two parallel narratives, Murakami draws readers into a mind-bending universe in which Bob Dylan, Lauren Bacall, 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 hilariously funny and a deeply serious meditation on the nature and uses of the mind.
