Invisible

Nico di Angelo's from a single-parent family, and lives permanently with his aunt for his mom is too sick to take care of him. He is constantly picked on in school by Clarisse, Clea, and Annabeth, the three sisters. But nobody stands up for him as they don't care for him at all. He's invisible to the rest. Or is he not? As he struggles through his school life and his studies, he realises that he's missing something. Something that he has never felt, genuinely since he was 9. And he thinks he has found it. AU, Percico slash, language, awkward moments.
