Cross my Heart || Loki Fanfic
Thalia left Olympus only days after she had come of age, running as far as she could from her more than a little complicated family. Alone and confused in a world so unlike her own, the Goddess slowly learns Earth's ways, cautiously living at the edges of the human society. For ten years she kept up her facade, invinsible and suffering the life of a mortal, but content with her choice.
Unfortunately, she didn't count on the Asgardians also making Earth their home. And she definitely didn't count on her own impulsive recklessness to attract the inconvenient attention of a certain infamous Prince.
