Save My Broken Soul [A Leo Valdez x Reader]

Just a couple heads ups. First, this is my first x reader so it might be bad. Second, I don't have a lot of free time so I might not update on a regular pattern. Third, I suck at descriptions so I'm trying my best here.
(Spoilers and dark topics. I DO NOT OWN ANY OF THE CHARERTERS UNLESS I SAY I DO)
Y/n L/n was a demi-god. Sounds great right? Well think again. Her mother died at child birth, and no one knew her father. So she's been in the foster care system for her whole life. She loved her first family, it was an old couple that raised till the age of four when they both passed. Her second family treated her like garbage. She ran away after a month. Her third, abusive. She was too scared to leave for ten years. Then she got up the courage and left, but the foster care people found her again and put her in 2 more homes (All witch rejected her, or she ran away from) before she ran away yet again where she came across a group of four teens, Thalia Grace, Annabeth Chase, Grover Underwood, and Luke Castellan. They took her to Camp Half-Blood but Thalia didn't make it. Y/n was claimed the daughter of Poseidon shortly after Thalia's death and when Percy came she was ecstatic, quite the flip from her normally cold personality. She started to heal from her past, but then one day she woke up and her wonderful brother was gone.
