Grace (You), now 16 years old, is the daughter of the war god Ares & the best fighter in all of Camp Half-Blood. Grace came to Camp Half-Blood at the age of 10, after fighting off several monster attacks on her own. Her mother gave up on her early, and she fought her way through the streets of Brooklyn until Luke Castellan found her. She joined him and Annabeth Chase, and the three became like a small family growing up together, although Grace could never fully confide in anyone. Since then, Annabeth, who is like a sister to her, and Luke, who is like a best friend, have been her closest confidants. Even as a child, she was fierce, brave, and full of anger, a born fighter, and no one dares to mess with her. She talks little, trains a lot, and doesn't let anyone get close to her. Her glowing green eyes rarely betray her thoughts, and she only speaks when necessary. She prefers actions over words & trains harder every day than anyone else in camp. She loves the camp, but she doesn't want a leadership role. Responsibility feels like a promise she can't keep. Instead, she fights. For the safety of others. Percy Jackson arrived at Camp Half-Blood after being attacked by a Fury at his school. At first, he didn't know he was a demigod. After several mysterious events, including an attack by a minotaur, he was seriously injured & taken to the camp by Grover (his satyr protector) & his mother. His mother disappeared in battle, & Percy made it to the camp with his last bit of strength. There, he woke up in the infirmary & gradually learned about Camp Half-Blood. Luke Castellan was one of the first people to care for him. Luke showed him the training areas, explained the world of the gods, & later even gave him a special sword, Backbiter. When Percy was new to camp, Grace saw him as a risk. She observed him from a distance, tested him in training, & rarely spoke to him, if at all. Although Luke was friendly to Percy, & annabeth tried to be nice to him, Grace didn't trust him.

Nevertheless, when they embark on a mission- Annabeth, Grace, Grover, & Percy, to find the stolen master bolt & prevent a war between the gods, Percy learns to trust his powers & decisions as they face Furies, Medusa, Echidna, Ares, & other dangers. They discover that the true traitor is not a monster or an alien enemy, but Luke. Grace & Annabeth's longtime friend and role model who, driven by his deep resentment against the gods, manipulated Percy, stole the bolt himself, & deliberately ignited the war. Meanwhile, Percy refuses to accept Luke's distorted view & instead strengthens his own moral compass. Annabeth realizes that Luke's escape & his alliance with darker forces are only the beginning of a larger conflict, one in which they must unite. After Luke's betrayal, Grace and Percy grow much closer, she begins to truly respect Percy, not just as a teammate, but as someone who does the right thing despite the chaos and fear. Percy understands that Grace is actuelly the kindness, sweetest, and funniest person, as she grapples with the loss of Luke. Although they sometimes tease or argue, they feel increasingly safe with each other, knowing that the other will always be there. However, Percy went back home for the summer holidays to New york, & Grace, Annabeth went to her aunt. Percy walked with Tyson at the side by the streets, before a car stopped before them, they realised that it's just the grey sisters, then the door opened. Grace put the cap down, the one which made her invisible while she went out off the car. Before Percy could say anything, spoke Tyson up.

Tyson - "Wait- You're Grace, right? Percy talks about you all the time."

Percy - whispered "Tyson?"

Tyson - "What? You look at her picture all the time, right?"

Percy sighed, while he shaked his head at Tyson. Ignoring it, while he stepped a bit closer to Grace & said.

Percy - "Uh, I thought you were in Virginia with annabeth and your aunt. Grace, what's going on? Is everything alright?"
