It's not an absolutely unique beginning, but in this day and age, that would be hard to find. The language, writing style is great. Very rarely am I able to completely just delve completely in the story because I am so often held back by the style of writing. This was definitely one of those times. I am thankful you empowered Eleanor, formerly so quiet, in the second chapter. It may be a personal preference but I am a sucker for quiet female main character's who reach boiling point and actually react, instead of pushing it all the way back down. Extra points for making Max so triggering, I wanted to punch him too because of what he said about Simon.
Read the story now
In paragraph 13 on your first chapter, there seems to be an incomplete sentence that looks like a typo.
Overall, I would definitely come back to reading this after this review. I'd like to see where Eleanor ends up :)
