A review of your second chapter as requested.
As I read this it bought me back to the first chapter, which was great. I could remember things and relate them to what I was reading now. It might be worth mentioning both their names in the first sentence again though, just to remind the reader and set the scene.
I think I am getting the true gist of the situation Ellie is in and the awful McKenna. There is a lot of detail though, about people, feelings and description of the location. This is fine, but could be a bit too much for some readers. Maybe hold off on some of the scene setting details a little if it isn't 100% necessary.
There are a few areas where I think you need to bring Ellie into it without needing to explicitly state the detail e.g.
A couple of metres in front of her were pair of women dressed in army combats.
She noticed a pair of women dressed in combats.
This then flows nicely into the thoughts she is having and just brings the reader in a bit more in my opinion.
There are a few missing commas and occasional grammatical mistakes, which you'll pick up with another few proofreads. For example:
The interior was surprisingly cushy with soft leather seats and foot rests. It was spacious too despite the backseats being occupied by a rolled up sleeping bags, quilts and blankets, and pillows.
All in all, I'm enjoying reading this, it just needs a few tweaks here and there and some more proofreading. Keep going.
