Quick recap
The Master of Jordan College gives Lyra the alethiometer. Roger vanishes, and Mrs. Coulter takes Lyra to London. Lyra learns Coulter runs the child kidnappings, escapes and is taken in by the Gyptians, who tell her Coulter is her mother. In our world, Will Parry looks after his mother while Lord Boreal, who crosses between worlds, watches him. Up North, Lyra helps Iorek recover his armor, finds Roger at Bolvangar and wrecks the machine that cuts children from their daemons. Lyra brings Roger to Lord Asriel, who severs the boy from his daemon to open a bridge to another world. Roger dies. Lyra follows her father across, and Will finds a window in the air.
