When the zombies rose, we thought the world ended. It didn’t—it just broke, in a way we couldn’t fix. And we found ways to continue, reasons to fight. Faith. Family. Politics. Obsession. The most dangerous of all— hope . But when all of that is stripped away, and nothing remains but rage and betrayal—that is the true end of the world. Return to the World Without End, for a final battle for hope and survival in the exciting conclusion to Nazarea Andrews’ phenomenal series.
