Maddy's mother says that right after Maddy's father and brother died, Maddy got very sick, and her mother, not wanting to lose her, decided she had SCID, and needed to be kept away from the world. Maddy is mad at her mom and can't bring herself to forgive her. Maddy flies to New York, where she sent Olly on a mini scavenger hunt that led him to a used bookstore where she was waiting for him.
