Despite that, Lina is desperate to continue writing young adult books. So, when her ex-husband, Jon Cote, who is a private investigator, invites her to join an undercover operation at Emerson Academy, she can't say no. She agrees to join "Operation Superglue" and is shocked beyond belief to discover that Jon has been posing as the school's substitute art teacher for months and without any leads in a case of several missing teens.
Now an undercover high school senior, Lina learns that today's society is worlds away from anything remotely familiar. And, with her ex-husband back in her life in more ways than one, Lina soon realizes that the choices she made in the past may not be as permanently stuck as she had once assumed.
