I read this when it was new, and I had a child in preschool. It was very good. And I never, ever want to read it again.

There's a zombie outbreak in an elementary school, a cascading failure of one preventative measure after another, and it follows how one teacher manages to get some of her students out alive. At a terrible cost.

It's an extended metaphor for school shootings, but years later, during the first year of the COVID-19 pandemic, schools reopened with children entering the campus one at a time after a health screening (temperature checks, not blood tests), sanitizing everything...and then I saw a picture of a classroom with individual transparent barriers around each desk.

At least Covid doesn't turn its victims into mindless killing machines.
