Warning! This page contains spoilers for The Hidden Oracle.

Margaret "Meg" McCaffrey is a twelve-year-old demigod daughter of Demeter, living on her own in Hell's Kitchen, Manhattan. After Apollo had been forced to live as a mortal, Meg saves him from being mugged. When she learns that he needs to be a servant to somebody, in order to return to Olympus, she claims him.


Early Life

Not much is currently known about Meg's early life, only that she was born to the goddess Demeter and an unknown mortal man, and that the god-emperor Nero killed her mortal father when she was still very young, and proceeded to take in and raise Meg as his own daughter. Through his sophisticated manipulation over the years, Nero was able to manipulate Meg into believing that he and the fearsome malevolent Beast were two separate people.

The Trials of Apollo

The Hidden Oracle

Meg threw trash at two muggers while they were mugging the former god Apollo. The former god feels that they are being watched and takes her to Percy Jackson's apartment. Sally Jackson gives her spare clothes. Percy decides to drive them to Camp Half-Blood.

Nosoi follow them, forcing Percy to crash his car in an orchard. The trio tries to fight the nosoi. Meg unintentionally summons a peach karpoi to fight off the nosoi, who bit a nosos head off then proceeded on finishing the remaining nosoi, even if they tried to retreat. Meg named the karpoi "Peaches". Using the western border, which is said to be wilder than the eastern border because of the heavily enchanted hills and woods, Meg, Peaches and Apollo made their way to Camp Half-Blood. She swings from tree branches and cartwheels through the mud. Apollo starts to hear voices when they reached the woods, causing him to collapse. Meg tried her best to reach Camp Half-Blood while bearing most of Apollo's weight and unknowingly talking to the trees to tell them to get out of the way. As soon as they reached the camp, Apollo passed out.

Will Solace mentioned that while Apollo is asleep, Meg poked Connor Stoll in the eyes and kicked Sherman Yang in the crotch.She and Apollo speak with Chiron about the recent disappearances of a few campers. That night at dinner as Sherman and Connor try to get revenge on her Peaches appears and slams Sherman's face on the ground and starts yanking out large chunks of Connor's hair. Soon after this she is claimed by Demeter. Billie Ng then takes her to cabin four.

The next morning Apollo talks to her at breakfast. She says she had trouble sleeping in her new cabin due to allergies. He asks her where she received her siccae blades, but she tells him to stop. They are paired up for the race and get lost, during which they wind up below Delphi and overhear a conversation between Python and the Beast. She is terrified by the ordeal but Apollo drags her away and they find the last golden apple and return to the Forest. Their binds unlock and they run back to camp. 

The next day she, Apollo, Chiron, and Rachel Elizabeth Dare head to the Oracle's cave where they talk about Triumvirate Holdings, an organization that has financially backed both the Titan's Army and Octavian during their respective wars with Camp Half-Blood. Apollo then says he has other Oracles and that one might be in the forest. The next day she and Apollo head into the Forest to find the missing campers. They come across a geyser god who they ask for information about The Grove of Dodona when they are attacked by a swarm of Myrmekes. After Apollo breaks his oath on the Styx, Meg is taken by them because of this. 

She is then freed by Apollo and after they get pass the Myrmeke queen they reach the atrium of the Grove, where they are greeted by Nero, who reveals that he is Meg's step-father. Apollo tries to tell Meg that he is going to destroy the grove, but she does not listen. She then forces Apollo to help her open the gate to the grove where she realizes Nero is going to burn it down. As Nero is about to set Austin Lake on fire, Peaches comes and stops him. She and Apollo run into the grove where he puts his wind chimes up and hears a prophecy. Meg frees Apollo from her services and says to do what he wants now before going back to Nero. 


Meg was described by Apollo as "small and pudgy", with dark hair chopped in a "pageboy" style and black cat-eye glasses with rhinestones in the corners. When Apollo first met her, she was wearing red sneakers, yellow tights, and a green tank dress. He thought she was dressed like a traffic light. She wears a green tank dress, black leggings, and a pair of red sneakers, to which she's apparently attached. Her voice was described as nasal and bossy. She also wears two gold rings, which she can transform into two Imperial Gold siccae blades.

After being cleaned up and dressed in more appropriate clothes by Sally Jackson, Apollo realized that Meg was a shockingly pretty young girl, with her dark pageboy hair shining glossy from being brushed, her face round, and she had an elfish springtime aura that reminded him very much of dryads.


Meg is brash but playful. She can be tough and easily defends herself, such as when she fended off Cade and Mikey.

However, she also hides the more fearful side of herself, as she is terrified of Nero to the point where she obeys him sourly out of fear of herself getting hurt or even worse.


  • Chlorokinesis: As a daughter of Demeter, Meg has absolute control over plants, manipulating them to a multitude of effects.
    • Plant Telekinesis: She is able to telekinetically manipulate fruits and vegetables, thus saving Apollo from two thugs.
    • Plant Sensitivity: She can sense the location of various plants with superhuman precision, this is seen when she was able to quickly detect the odor of a golden apple in the Labyrinth. She later claims to have the ability to "hear" trees growing.
  • Culinary Arts: As a daughter of Demeter, Meg is a natural cook.
  • Karpoi Summoning: As a daughter of Demeter, Meg is able to summon Karpoi, like when she summoned Peaches.


  • Much like Luke Castellan, Meg is revealed to be a double agent of the series' main antagonist (Kronos and Nero respectively) near the end of the first book in one of the Camp Half-Blood series (The Lightning Thief and The Hidden Oracle respectively), though it should be noted that unlike Luke, Meg was shown to be quite apologetic and hesitant when it came to her true allegiance.
  • Meg is the second demigod known to wear glasses, the first being Jason Grace.
  • She had a brief crush on Percy Jackson, but lost interest when he said he had a girlfriend.
