Richard Mayhew is a young London businessman with a good heart whose life is changed forever when he stops to help a bleeding girl—an act of kindness that plunges him into a world he never dreamed existed. Slipping through the cracks of reality, Richard lands in Neverwhere—a London of shadows and darkness, monsters and saints, murderers and angels that exists entirely in a subterranean labyrinth. Neverwhere is home to Door, the mysterious girl Richard helped in the London Above. Here in Neverwhere, Door is a powerful noblewoman who has vowed to find the evil agent of her family’s slaughter and thwart the destruction of this strange underworld kingdom. If Richard is ever to return to his former life and home, he must join Lady Door’s quest to save her world—and may well die trying.
