The Subtle Knife ( Dark Materials 2)

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. 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, their destinies are bound together, until they are split apart.
