I really like the film The Girl with all the Gifts and it turns out that the book is excellent too. There were enough mentions of (basic) mathematical concepts that I wondered if the author was a mathematician but Mike Carey studied English at Oxford.
This quote probably tells you a lot about the book:
"Please remember, Doctor, that the subject presents as a child but is actually a fungal colony animating a child’s body. There’s no place for sentiment here.”
Much of the book is told from the point of view of one of these fungal colonies.
The only other zombie (or zombie-adjacent) fiction I've read was World War Z and that was boringly ordinary by comparison.
