He didn't know it would be her to get him smiling like a goofball, in fact he'd never thought it would be her to make his heart feel like it was 5 times the size of how big it usually is. Lately, she'd been feeling the heat rise to her skin a lot."And how happy we were.""We're not happy now? hold on to that happiness when I tell you what I'm about to tell you."She narrowed her eyes at him. ""mhmm….""Whatever, anyway the Stoll brothers kind of used their cameras and… And their High Def.""Because that makes it a lot better.""Well… The only thing he did know was that he was more than happy. and their high definition camera."Percy's eyes widened.

She is first cousins with Magnus Chase, who's mother is her paternal aunt.

She first appears in the first novel of the series, The Lightning Thief.
