His Dark Materials

Lyra is a orphan who lives in a parallel world in which theology, science and magical are entwined. Lyra's hunt for a friend turns into a search to understand a phenomenon referred to as infantry, and finds a sinister plot involving kids that are stolen. She is later joined on her travel Will, a boy who owns a knife which could cut on down windows between worlds. Both young folks are caught up in a war against celestial powers which ranges across worlds as Lyra finds the facts about her parents and her prophesied fate.
