When a raging fire destroys an entire street in a suburb of Seattle, seventeen-year-old Wynne Frazier's home becomes one of the victims. Taking her parents and belongings with it, she's lost a place to call home. A mysterious, glowing symbol appears from the ashes of her former home, throwing Wynne, and her childhood friend, Atlas, down a path they could have never expected. An underground world of a magic called "Soultapping" laid right underneath their noses, where people can harness the energy from their own souls, or Cores. But her discovery might be a glimpse into a global threat she could have never imagined. And somehow, she might be the way to stop it.
