Strong world building, well-developed characters, and a plotline about fighting back. It took me a while to pick this up, but I am glad that I finally did! It sets up the next two books in the trilogy, and I thought most of the characters were well-rounded. With the excpetion of a few of the group of girls Lei is in. There's this interesting dichotomy between people saying that being a Paper Girl is such an honor, but it's clear that it's not. 

The relationship happened a little fast for me, but I do think it has the opportunity to be developed in future novels. There was a bit of instalove here that isn't my favorite trope. But I am interested in seeing where it goes next!
