I'm always reading something, usually multiple books at a time.
In Volume 30, Eugene and a small contingent from his (and Rick's) community reach a contingent from the community of Stephanie--the person on the other end of the radio communications Eugene has been engaged in for a while. Understandably, both groups are wary, and long-time readers can appreciate the risks inherent whenever the the characters encounter new groups.
I don't want to give away any surprises, but there is a doozy of a surprise awaiting one of the core characters, at the community Stephanie belongs to. There is a big "Wow" moment. It soon becomes clear that this large, complex community operates under a fundamental philosophy that is quite different from that of Rick and and his neighbors.
Will those differences lead to more conflict, or is mutual benefit in the characters' not-too-distant future? We will have to look to volume 31 and beyond to find out.
