While waiting for the camp council to start, Lou Ellen from the Hecate's Cabin was playing "got-your-nose," except that Lou really had magically disconnected Miranda's nose from her face and she was trying to get it back. Thankfully, Chiron requested that Lou give Miranda's nose back so they could start the meeting.
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.
Miranda is mentioned along with Katie Gardner trying to help calm the nature spirits.
Miranda is one of the campers to vanish. It is later revealed that she and the other missing campers are being held captive by Nero near the Grove of Dodona. When she and the others are free they fly back to camp on female Myrmekes. When they arrive back at camp the Colossus Neronis is attacking. She, Ellis Wakefield, and Cecil Markowitz distract the automation while Apollo, Austin Lake, Kayla Knowles, Will Solace, and Nico di Angelo take the automation down. She is reunited with her boyfriend, Sherman Yang in the end.
All that is known about her appearance, is that she has green eyes, the color of new foliage, according to Apollo.
- Chlorokinesis: As a daughter of Demeter, she has absolute control over plants.
- Culinary Arts: As a daughter of Demeter, she's a natural cook.
- 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.
- Her last name "Gardiner" probably has to do with the fact that she is the daughter of the agricultural goddess, Demeter.
