Zoe was seen and mentioned when Jason Grace, Piper McLean, and Leo Valdez visit Midas's mansion in Omaha. It turns out that Midas never really gave up the magic touch, he claimed that Zoe was so annoying that he ended up turning her into gold again and keeping her that way. Her statue was described as looking extremely annoyed, as if she were complaining, “Dad!”
When Jason summoned a thunderstorm above the mansion, he tore the ceiling off with a lightning bolt and Zoe, along with the rest of her father's victims, return to human form. It's possible that she helped them kill him since he turned her into gold even though Midas was her own father. She is never mentioned afterwards.
- She is probably Demeter's daughter, because her brother Lityerses mentions Demeter being his parent in The Dark Prophecy.
- According to Lityerses, she talked a lot. Its also said so by her father that she was so, since he said “Exactly!” once Lityerses said it.
