I read about a hundred pages of this and then gave up in disgust. I liked the centre of the story being friendship between two women, but I didn't actually like either of the women. I'm fine with unlikable heroines, but I think I was supposed to like them? They were both selfish, judgemental and cruel, and... why would I want to read 400+ pages about them?
Also the only person of colour was immediately slut shamed, and the heroine didn't understand why the group of survivors wanted to stop and look for their own families, instead of going straight to hers. Yay!
On the bright side, the book was free.
