I hate the zombie craze, but this book was a finalist for the Detcon1 award for middle grade and YA Speculative Fiction, so I had to read it as a voter for the award.
I'm so glad I did.
The descriptions on the book talk about how it will make you think about where your food comes from, but my favorite aspect of the story was how it illustrates how damaging to families some of our immigration policies are, and how unfair to kids who have grown up in the US but weren't born here -- people who were brought here by their parents when they were babies.
It also does carry a strong message about how you should keep in mind that food corporations may put their profits ahead of public safety and any industry that tries to penalize people for telling the truth about their practices isn't to be trusted to be producing things for the public to eat.
Ultimately, it's about friends working together to fight several kinds of dangers, including bullies both alive and undead. An uplifting story with rapid action and fine messages to boot.
I gave it five stars (out of five).
