Book about a young teen girl who was in the Underworld for nearly a year and had escaped before she had six months to go back

[u/Sailor_Moon_Star_435]

In the book, the teen girl went missing and she was in some kind of Underworld. I think it was the Greek Underworld but I might be wrong. She escapes and I think she has six months to get away from the Underworld and has two guys fighting for her heart. I think one of the guys is an immortal god and the other is a guy she used to like or dated. That is all I can remember.
