Liked the story and characters, seems to do well compared to others I have read like this story.
Main complaint, picky I know but.. If you are to have a character that is from a specific background and you are going to highlight something about that background make sure you get phrasing correct. It is not the “Marine Corps Anthem” it is the “Marines’ Hymn.” And if you’re going to quote it, at least get the lyrics correct.
