Leah and Rayford Steele clash as they stumble at trying to work together, their personalities colliding. Leah's first Trib Force undercover mission, at the midpoint of the Tribulation, takes her to Belgium to try to communicate with Hattie at the Belgium Facility for Female Rehabilitation (BFFR), or "Buffer." There, she meets Ming Toy, another believer with a strategic position inside the Global Community. Ming helps Leah avoid suspicion and incarceration, and Leah returns to Illinois.
She helps out at Operation Eagle as a nurse, and then goes to live with a co-op pilot and his wife when the Chicago safe house is compromised.
