Amaryllis Potter never fit in, but neither did her brother Harry.
She always had unexplainable things happen that her brother never experienced, and yet he was the only one to believe her.
When a letter arrived for both of them, Amaryllis had seen it as a way out. It didn't matter how absurd it sounded when they called her a witch or the owl they entrusted their letter to hated her for no reason.
What awaited them was unveiled truths no one knew about and the origins of her birth that made all the Greek myths she loved to read and hear about more than what they were: real. And she was tangled in the middle of two impending wars with two half-brothers on both sides.

Cheers to Apollo for making you | Draco M x Percy J | ❪ 𝘁𝗲𝗿𝗺𝗶𝗻𝗮𝘁𝗲𝗱 ❫
Draco knew he was a child of the gods through his mother. Through the stories whispered at his bedside and dying candlelight, through tales of which any semblance of truth is washed by the never ending marching of time. His mother always spoke of a peculiar little haven of which the children of gods and many more creatures of old thrived. Draco never thought he'd be just like them. ___________ Or In a world of which Demi-gods exist, where myths and religion mold together in a complex jungle of threads and knots. Draco is the child of his mother and mysterious god that im pretty sure has cursed him of a million other siblings. PJO x HP crossover season Book cover are made by @urJellyfish1Complete

Then, perhaps, all she had to do was answer questions about whether she really hailed from a certain village in Switzerland: she did not. Alas, when she was thrusted into the realm of non-magic, she was not welcomed. As much as nobody had the slightest clue about her heritage, none was fooled by her mismatched eyes. One light, one dark: it was the epitome of evil. It did not help that strange things always seemed to happen around her, including a barn owl swooping into her dorm room on her eleventh birthday. She felt like she had waited her entire life for that moment. Her chance to turn her life around had finally come. There was not going to be time for friends, not that she would make any. There was not going to be time for boys; those were a waste. There was only time for study, because a basketful of O.W.L.s and N.E.W.T.s was her only ticket to leave behind what she had. It was time to reenter the world in which her name heralded wickedness and villainy--it was time to attend Hogwarts School of Witchcraft and Wizardry.
