Very good but brutal
I really like the series but I really despise the main character. He's more than plausible but combines the worst of teenaged self-righteousness with no acceptance of responsibility or gratitude. This is a mid-twenties male, not a child though he thinks like one. He seems a good model of what to avoid in oneself.
The characters are brutal and real with a lot of gory detail. The series background is composed of three sets of survivors. The first are the end of the world maniacs whose sole purpose is to pillage and destroy any pocket of normality they encounter. How they will survive when they are all that's left, is a great question. The second set are the devolved who have burnt out any concept of building, growing or rediscovery and routinely practice cannibalism. They roam the countryside without plan or purpose except to eat whatever or whomever they encounter if it's not too difficult. The third set are the timid who look the other way when they discover their insane neighbors practising slavery, murder, etc. imagining that they are superior and also won't be next, if they don't disturb the neighbors. They tell themselves that cowardice is civility and the horrors visited on others is not their responsibility.
With a story like this, the end seems to be the well deserved extinction of the human race. I hope we are better than this but maybe we're not. I am definitely reading the next volume, if only to discover where the series is headed.
