Summary: A modern take on CS Lewis’ Screwtape Letters.
I remember reading CS Lewis’ Screwtape Letters when I was pretty young. I am not sure, but I think I was probably 12 or 13.
It was just enough humor and story for me to be able to read, while at the same time absorbing some good theology. I think that is what Matt Mikalatos is doing with Imaginary Jesus and Night of the Living Dead Christian (Bookwi.se Reviews), but there are not many other books that are trying to mix a light story wrapper on good theology.
