Needed to be fleshed out

To me, this book felt a little thin, like almost every aspect needed to be explored or enriched just a little more to make it something great. I would have liked the characters to show more interest in understanding Alice's invisibility power (especially since it's crucial to the plot) and for that power to be better incorporated into Alice's character development. The question of the morality of Alice's actions was only loosely touched on and never matters as much as it could or affects the characters' relationships. The middle section where Alice should be settling into her new role as the 'Beijing Ghost' and beginning to unearth her classmates' secrets is glossed over so quickly that there's not much sense of tension or development.

That's not to say it was a bad book however, what was there was good. The relationship between Alice and Henry was believably written and developed slowly as they worked together. What was best written were the class differences between Alice, who comes from a working-class family, and her wealthy classmates as well as Alice's fears of wasting her parents' hard work and investment in her future if she isn't always working and always the best. The rest of the story was too lighthearted and didn't have the tension or depth to support those themes all that well.

Overall, a decent, light-hearted teen adventure story that hinted at a lot more than it gave.
