After reading so many of Mcfadden's works, I've noticed several recurring themes and tropes. I was able to create a bingo card based off this and almost filled up the whole board. Even though some things are predictable, the book was alright. I liked the Raven ending but didn't enjoy the behavioral pattern of the teacher. I think my second least favorite thing was a repeating phrase that didn't need to happen. "Snapflash - the messages disappear after 60 secs" only needed to be said not every time someone opened the app.
