I’m looking for a book that begins with a girl running from a monster (possibly a Demon). She potentially has red hair and befriends a group of guys at her high school. One of the guys has plant powers at the very least there is a scene where they fight a plant. I remember she only dates one of them in the books (I think). I also believe a Greek god is mentioned (maybe Apollo). It is a series and at some point I believe she ends up in hell.
Not too certain about a lot of the details since it’s been so long. If you find it you’re my hero!
