Thalia loved pizza. Which really was unfortunate for her, because Artemis didn't like her hunters eating "unhealthy".
Thalia also happened to be an extremely disobedient person. So she would very often sneak out of her tent late at night and get herself a large loaded pizza. Artemis also despised coffee, saying it was a mans' drink, so Thalia ended up sneaking a lot of those too.
Her favourite pizza was Dominos, she didn't know why. But if they had a frequent buyers program, she'd be at the top. She ordered a large pizza almost every day, and it was a miracle she wasn't fat. Although Thalia suspected that had something to do with her immortality.
But one day, a tragedy occurred. She couldn't find a pizza place.
