A fun mashup of heroes and zombies, just like the back of the book says. The heroes are pretty heroic, and the zombie plague is horrific and fits the setting.
It’s a well written apocalypse, with a collapsed society and tightened boundaries that felt realistic. The book falls into a focus on the supers, with everyone else more an abstraction–people to save, protect, but not really interact with.
I’m mildly curious about other books in the series.
