Though ostensibly written for children, this heroic and heart-wrenching His Dark Materials trilogy is beloved by readers of all ages. These three novels unlock the door to parallel universes where demons and winged creatures live side by side with humans, and a mysterious entity called Dust just might have the power to unite the universes-if it isn't destroyed first. Lyra, Pantalaimon, Will, and the rest embark on the most breathtaking, heartbreaking adventure of their lives. The fate of the universe is in their hands.Lyra and Will tumble separately into the strange tropical otherworld of Citt�gazze, where adults are curiously absent and children run wild. Their journey is plagued with obstacles, some familiar and some horribly new, but it eventually brings them closer to Will's father and to the Subtle Knife, a deadly, ancient tool that cuts windows between worlds.
