After witnessing a god rape her sister, a naive nymph seeks revenge, risking her life in the process.

I want to echo what dpg said. The lead character who seeks revenge should be the victim. ?Sort of, "I spit on your grave" Meets "God of war" (The video game)

Agree with Richiev and FFF.

And "risking her life in the process" goes without needing to say so. ?That's always the implied stakes, especially when a character takes on a god.

And what about the rape victim? ?Why can't she be the one who seeks revenge? ?After, she's the one who has suffered the more, who has the stronger motivation.

?

Great start! But it feels a little vague. What kind of god? Does the nymph have any faults that must be overcome. How is she going to risk her life?
