Meg McCaffrey

Margaret "Meg" McCaffrey is a twelve-year-old Greek demigod daughter of Demeter, living on her own in Hell's Kitchen, a neighborhood in 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 so that the fallen god can return to Olympus, she claims him and travels with the fallen god to help him regain his godhood.

Early Life
Meg was born to Demeter, the Greek goddess of the harvest, and Phillip McCaffrey, a mortal man and botanist, in Palm Springs, California. She lived in Aeithales, a series of greenhouses built by her father. Her father cared for her greatly.

When she was five years old, her father was being threatened by Triumvirate Holdings due to his work in trying to restore the Meliai and they were forced to flee after their house burst into flames by orders of Caligula.

Living with Nero
They went east to New York City, where the god-emperor Nero separated her from her mortal father and proceeded to take her in and raise Meg as his own daughter. Before their separation, her father gave her a rose which was supposed to be a gift from her mother.

When she was six years old, Nero killed her father for the daughter of Demeter’s disobedient and crushed the rose, and indirectly blamed the daughter of Demeter for her father's death.

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, rather then the same man.

Appearance
When Apollo first met Meg in The Hidden Oracle, he described her as "small and pudgy", with dark hair chopped in a "messy pageboy" style. She wore black cat-eye glasses with rhinestones in the corners, and her outfit made Apollo think she was dressed like a traffic light: red sneakers, yellow tights, and a green tank dress. He also described her voice as "bossy and nasal".

After Sally Jackson cleaned up Meg and dressed her in more appropriate clothes, Apollo realised that she was a shockingly pretty young girl: her dark pageboy hair shone glossy from being brushed, her round face was scrubbed clean of grime, her cat-eye glasses were polished, and she wore new black leggings and a knee-length frock of shifting green hues, along with two gold rings that could transform into two Imperial Gold siccae blades. She also had an elfish springtime aura that reminded Apollo of dryads, and he noted that there was actually a resemblance between her and his first true love, Daphne.

Personality
Meg is brash but playful and often somewhat rude. She can also be tough and easily defends herself, such as when she fended off Cade and Mikey. Apollo describes some of the things she does as “Because Meg”. However, she also hides the more fearful side of herself. In fact, she is terrified of Nero to the point where she obeys him sourly out of fear of herself getting hurt or even worse. She closes up when people ask her personal questions. She is very protective of her past and usually doesn't tell anyone about it unless she wants to. She is also straight to the point and doesn't hide what she wants to say.

Later on, Meg becomes more willing to open herself to emotions, as shown when she saves Apollo from the water snakes in The Oracle of Trophonius through sharing her memories in a heartbreaking song, and pushes past what she is comfortable with to rescue him. Here, Meg is almost selfless as she sacrifices herself even though she isn't prepared for the Oracle and didn't drink from the Lethe and Mnemosyne.

She also demonstrates a sadistic and vengeful side. When going after Caligula she wants to kill the immortal emperor for destroying her home.

Abilities
As observed by Apollo, even for a child of Demeter (one of the six oldest Olympians), Meg was a remarkably powerful demigod, enough to warrant constant supervision. Nero himself trusted Meg with dangerous missions not just due to her fear of him, but also because of her strong powers and exceptional intelligence.
 * Dyslexia: Meg’s brain is “hard-wired” for Ancient Greek as opposed to modern English. However, as revealed in The Burning Maze, Meg is unable to read Ancient Greek.
 * ADHD: Meg has inborn battle reflexes.

 * 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.

Joshua
Meg appears to have a crush of the male dryad as she eyes him whenever she is at Aeithales with him and becomes nervous when he hugs her. After Apollo interrupted their conversation, she looked annoyed at him.

Philip McCaffrey
Meg was close to her father and had a loving relationship with him. She was devastated when he was killed and blamed herself. In reality, Nero was the one responsible for her father's death. However, Nero blamed the death of Philip, her father, on the Beast and convinced Meg that the Beast was a side of Nero he could not control.

Demeter
While they have never met, the goddess of the harvest has acknowledged Meg for her fighting abilities.

Nero
Meg is terrified of the God-Emperor and obeys him solely out of fear. However, she eventually escapes from him and joins up with Apollo.

Apollo
When she first met the fallen god, he was under her step-father's orders to become his master for his duration as a mortal. She eventually grew to care for him as a friend.

Leo Valdez
Meg first met Leo in ''The Dark Prophecy. ''Throughout the book, Meg travels alongside Leo, Calypso, and Apollo to fullfill the prophecy of the Grove of Dodona.

Piper McLean
Meg first met Piper in The Burning Maze. When Piper learned of Meg losing her father and her first home, she hugged Meg and, to Apollo's surprise, Meg thanked her.
