You can now read the first excerpt of Christ Formed in You over at the blog that is tracking the editing process. This is a section from chapter six - representing perhaps one third of that chapter - that will give you a feel for how the book will read.
We're now neck-deep into editing. Kevin has sent back edits on chapters two and three, along with some directed rewriting of chapter four. I am planning to sit down to work on these three chapters tomorrow afternoon and perhaps again one afternoon next week.
