The Subtle Knife

Lost in a new world, Lyra finds Will—a boy on the run, a murderer—a worthy and welcome ally. For this is a world where soul-eating Specters stalk the streets and witches share the skies with troops of angels.<br /><br />Each is searching—Lyra for the meaning of Dark Matter, Will for his missing father—but what they find instead is a deadly secret, a knife of untold power. And neither Lyra nor Will suspects how tightly their lives, their loves, and their destinies are bound together... until they are split apart.
