Her family is banished from the League, her kidnapper is on the loose, and now it is up to Terri to bring back justice for everyone. As she begins a challenging journey to uncover the truth about life behind the Dome and learn about love, Terri's priorities become a jumbled mess as she attempts to distinguish what is more important: family and honor or passion and revelation.
