‘Without this child, we shall all die.’ Lyra Belacqua lives half-wild and carefree among the scholars of Jordan College, with her daemon familiar always by her side. But the arrival of her fearsome uncle, Lord Asriel, draws her to the heart of a terrible struggle – a struggle born of Gobblers and stolen children, witch clans and armoured bears. As she hurtles towards danger in the cold far North, Lyra never suspects the shocking truth: she alone is destined to win, or to lose, the biggest battle imaginable.
