Tris and the gang head to Amity as expected from the end of the first novel, Divergent. There Amity decides that they don't want to be in the war, but will support both sides as a peace keeping area. With the ghost of her kills haunting her in broad daylight, Tris finds herself told time and time again that she should not get involved in anymore than she has for her mental stabability. When the Erudite charge into Amity headquarters all the Abnegation and Dautless can do is run. As a result they find themselves on a train to the factionless with weapons. Stories unravel and secrets are kept hidden from most and Veronica Roth tells a wonderfully twisted book.
