Miranda Gardiner

Miranda Gardiner is the demigod daughter of Demeter and the counselor of her cabin.

The Lost Hero
While waiting for the camp council to start, Lou Ellen from the Hecate Cabin and she was playing got-your nose, except that Lou really had magically disconnected Miranda's nose from her face and she tried to get it back. Thankfully, Chiron requested that Lou will give Miranda's nose back. During the camp council, Miranda is the counselor for the Demeter cabin, with no mention of what happened to Katie Gardner or how Miranda is the new head of her cabin.

Trivia

 * Miranda and Katie Gardner have similar names except in Miranda's name there is an "i". If this is an error by Rick Riordan, it is unknown.
 * While no explanation is given about how Miranda is the head counselor for her cabin, it can be assumed that Katie is not a year-rounder and only stays during the Summer. Additionally, Miranda could have possibly taken Katie's place via a duel for the counselorship of Demeter cabin, or Katie could've stepped down.
