In a universe somewhat like our own, children are beginning to disappear from cities around England. For Lyra Belacqua, a half-wild orphan girl living at Jordan College, Oxford, the kidnappings are just another excuse for games, battles and tall stories - until her best friend Roger is reported missing. Vowing to rescue him, Lyra embarks upon a journey to the savage North, where physicists and theologians alike are conducting controversial research into the nature of something known only as 'Dust'. Apart from her friends the gyptians, her only guide is a curious golden instrument called an alethiometer. If she is to survive her ordeal, she will have to learn to interpret its cryptic and peculiar messages. 432
