Lyra and Will, two ordinary children on an extraordinary and otherworldly quest, have fallen into unspeakable danger. With help from the armored bear lorek Byrnison and two tiny Gallivespian spies, they must enter a gray-lit world where no living soul has ever gone. All the while, Doctor Mary Malone builds a magificent amber spyglass. An assassin hunts her down. And Lord Asriel, with troops of shining angels, fights his mighty rebellion. As war rages and Dust drains from the sky, the fate of the living-and the dead- finally comes to depend on two children and the simple truth of one simple story. The Amber Spyglass reveals that story, bringing Philip Pullman's His Dark to an astonishing conclusion.
