Lyra Belaqua is content to run wild among the scholars of Jordan College, with her daemon familiar Pantalaimon always by her side.

And as she hurtles toward danger in the cold, far North, young Lyra never suspects the shocking truth: She alone is destined to win, or to lose, this more-than-mortal battle.
