It was different from the first three books. Reynie, Sticky, Kate, and Constance are all much older. With the appearance of a new member and the rise of more ten men, they are forced to travel to where it all started- the institute. They change over those years. Sticky wants to be called George, Kate abandoned her bucket, and Constance is different than before. It wasn't the amazing book I expected it to be and I think TLS lost his writing style a bit, It dosent pull you in as much anymore. But overall it was OK.
