Great book. Got it because a friend was running a post-apocalyptic setting with the previous version, so when I saw the update published I threw my money at it immediately. Some great improvements on the previous book, and I've still barely touched the entirely new sections, so money well spent. Also, the author has made two large updates since release correcting small errors and imbalances, as well as making available a fillable pdf character sheet, so it's lovely to see such care and attention paid. Thanks for all the hard work.
