Philip Pullman takes readers to a world where humans have animal familiars and where parallel universes are within reach. Lyra is rushing to the cold, far North, where witch clans and armored bears rule. North, where the Gobblers take the children they steal--including her friend Roger. North, where her fearsome uncle Asriel is trying to build a bridge to a parallel world. Can one small girl make a difference in such great and terrible endeavors?
