Love, Fate, and Demigods

Elli, Anna, and Luke are all demigods. Elli was rebellious and left the training camp, Luke her boyfriend leaves to search for her and bring her back. Anna was sent out to find them. Luke and Elli are closer to finding each other than they think, until Anna unites them.
Now it's up to them to unravel their past, and fix what they've done. Why did they forget about camp, and their parents that are gods? Why can't I tell you more?

Because I'd ruin the story!!!!
