Brian D McLaren. A New Kind of Christianity. http://www.amazon.co.uk/New-Kind-Christianity-Questions-Transforming/dp/0340995491/
I'm reading it on Kindle but would have preferred it in Logos. There are a few Brian McLaren titles in Vyrso, but not this one.
It seems to be an important book. A few chapters in, it is certainly helping with some of the questions that I have been asking for the past 20 years.
