- The ongoing story arc - getting stalked. Not just by any stalker (which is scary enough in itself), but one who can follow almost every move you make in public by hacking into traffic and security cameras.
- The very concept behind Lindy's website, never4gottengroup. Full of people who, just like Lindy, have had people they love disappear without warning, never to be heard from again... and the police aren't finding them.

- After Lindy finds out that Sophie has been captured and close to death, she takes off to rescue her friend.
