Im finally finished The Amber Spyglass and here is how it went. So Lyra and Will manage to free the dead. They must go to another world to get there daemons/souls back and unfortunately, there is currently a huge battle between Lord Asriel forces and Metatron's (god's regent) forces. They manage to get there way through the battle and retrieve their damons. However in the process they "kill" god. God, or the authority, is kept inside a crystal cage. Lyra and Will set him free not knowing that he was god. When he came out of the cage he dissolved into the wind.
They travel to the mulefa's world now and meet Mary Malone who is currently trying to stop the dust (particles that are supposed to make everything good) from leaving the world. When Will and Lyra fall in love, this problem is solved because the dust settles around them and stop escaping. However Will and Lyra find out that they cannot stay together because everyone time the open a window to another world, dust is lost. In the end they seperate and go back to each other's world.
