This one definitely dove into the characters more. I like Nadir more and Lor less. 
In my opinion, no youngest sibling acts this way. Like she is somehow responsible for her older siblings it doesn't come across as realistic.
Nadir constantly calling Lor "inmate" is ick. Especially since at this point, it's obvious they are into each other. I love an enemies to lovers and banter, but this slow burn is too slow for me. Lor is annoying in this one, I'm hoping that turns around in the next one.
