The trilogy that establishes Lyra's world and the wider multiverse, following Lyra Belacqua from her childhood in the cloistered world of Jordan College, Oxford through a journey that takes her across multiple worlds and places her at the centre of a war that will determine the nature of consciousness itself. Beginning with Northern Lights, which introduces the world's distinctive theology, daemons, and the mystery of Dust, the trilogy moves through increasing philosophical and emotional complexity to a conclusion that engages directly with Milton's Paradise Lost and the question of whether innocence or experience is the greater human gift.
