I just finished off an amazing little book by Mike Bryan called The Afterword. The conceit of the book is that is not an actual novel, but is instead the afterword to the newest edition of a novel -- a novel that in our world does not exist. The novel for which this is the afterword is "The Deity Next Door," which is the story (non-existent) of a modern day messiah figure, dropped down into the middle of 21st century New York.
Within this bizarre set-up, Bryan is able to effortlessly discuss a range of theological issues and topics. He takes the topic seriously, and is clearly conversant with the language of theology and evangelicism. Not everyone who writes on he topic knows much about it, but Bryan clearly does. Very intriguing and thought-provoking.
