This is the second novel in the trilogy and picks up right where Divergent left off. So Tris, Four and their uneasy alliance are sort of on the run after the vicious attack by mind controlled Dauntless on Abnegation.
Their society is more divided and ill at ease with itself than ever as our heroes have to seek allies and shelter with other factions as well as turning to the factionless for help.
This is a great book. It’s action packed and exciting as well as taking time to explore more of the themes of Tris’ strange world and to follow her struggles to recover from the guilt at having killed a friend to defend her family in the last book.
I would say a downside is that Tris’ behaviour is a little infuriating at times. She is needlessly (in my opinion) secretive with Four, who has made his love for her clear. But I can see why the author has her act this way and she is trying to show just how messed up Tris is by the trauma and losses of the last book – she’s very human, acting illogically and making mistakes.
It’s good to get to know other factions a little better too. Both the readers and Tris get to see that there are many members of factions who don’t neatly fit into the personalities they have been assigned.
The novel ends with a wonderful big reveal and a tantalising cliff hanger that has me impatient to read the next book!
