Yep, that's right.
It's called Dead Petals: An Apocalypse.
If your own reading habits traverse little in zombie novels, you might be intrigued by a few lines of explanation from Eric in this interview. He says:
The kind of preying on each other, the kind of feeding off of each other in a way that kills each other in zombie movies, that is the world we live in. It is being shown metaphorically and physically in a literal way in a horror movie, but I think that horror is real.And:
Beneath the nice appearance I think the real world we live in is much closer to the horrors and the beauties of the book of Revelation and to the kind of portrayal of the world we get in a zombie movie. A lot of dead, endlessly empty people feeding on each other.And:
All the characters are running from something, all of whom are confronted, all of whom sin and all of whom find grace.Perhaps the eerie fascination with death that seems hard-wired into fallen people is an unexploited point of connection with the gospel. Eric believes so, and I think he is right.
And who wouldn't want to read a zombie novel by a seminary professor who teaches like this?
