This was kind of a slow burn, mostly dealing with the fallout of the previous volume. It's one of those books that feels like the calm before the storm and allows the characters some time to breathe. It's interesting to see how far these characters have come, the Rick of this book is so far removed of the Rick in the earlier volumes. He's aware of the mistakes he's made in the past and is desperate not to repeat them. Michonne has also changed a lot but I don't think she was quite ready to acknowledge it. 
 I love that Rick decided to keep Negan alive, not only because it marked a turning point in the evolution of Rick Grimes but because it's clear Negan's story isn't quite done yet.
