Luke Garner Timeline and Summary

Luke says goodbye to the outdoors as the woods are cut down he is forced to live inside.
Luke's parents take mega precautions, like making him stay in his room.
But he's able to sneak out one day when the window blinds are left down.
After being caught and sent to his room, Luke sees a mysterious face in the window of his neighbor's house.
He observes the family and eventually concludes that they have a third child as well.
After lots of thinking and planning, Luke sneaks out of his house to meet this other third child.
Enter Jen Talbot, Luke's new (and only) friend.
She tells him all about the shadow/third children rally she's planning.
Luke hems and haws and finally tells her, a few days before the rally, that he doesn't want to go.
They fight, but Jen still sneak into the Garners' house before she leaves to say goodbye to Luke.
After hearing nothing about the rally on the news, Luke goes over to Jen's house to look for her.
Instead of Jen, he finds Jen's father and learns that she was killed at the rally.
The Population Police show up at Jen's house and Mr. Talbot hides Luke in a closet.
When the coast is clear, Mr. Talbot indicates that Luke is going to need a fake I.D. if he doesn't want to get caught by the Population Police.
Luke agrees and eventually tells his family everything that has happened.
He leaves the farm with Mr. Talbot with the new identity of Lee Grant.
