Picking up right where The Secret Commonwealth left off, this story finds Lyra alone in a city haunted by daemons, searching for her beloved Pan. Malcolm Polstead isn't far behind, searching for Lyra. And they are both racing toward the desert of Karamakan, following the trail of roses said to hold the secret of Dust. Their allies and enemies are converging on the mysterious red building at the heart of the desert: Marcel Delamare and the military might of the Magisterium; the radical Men from the Mountains; scientists, scholars and spies; troops of witches and other people of the air. And awaiting them all is a previously unseen and chilling new threat that will change everything. The intertwining odysseys of Malcolm and Lyra, their journeys both internal and external, will test their limits and challenge even their most dearly held beliefs. As ever, Philip Pullman is using the language of fantasy to illuminate our world and to explore the deepest questions of what it means to be alive and awake to all the splendors and horrors around us. The extraordinary novels of The Book of Dust speak powerfully to today's readers and will take their place alongside the forever-favorites of His Dark Materials.
