Crossway series "Theologians on the Christian Life", especially Bonhoeffer, Schaeffer and (upcoming)

On the Gospel Coalition website I happened upon a recent article where Prof. Nichols summarizes some content from his latest book "Bonhoeffer on the Christian Life" - it seems to be a very worthwile introduction into Bonhoeffers life, work and -especially- faith. 

Checking out the Amazon page, I noted that this book really seems to be a large gap in my library, since it seems to provide some accessible inroads into the large corpus of Bonhoeffers work - I own nearly "all" of it but rarely read it.... Don't take my words for it, Crossway offers a 50-page preview here.

I made ready to write up a suggestion here, then I noted that this book is only one of a series. Of course I think "Schaeffer on the Christian Life" is something we need in Logos, too!

Actually the whole series - there's one on Warfield, too, Wesley will be released end of this month and Michael Horton is busy writing up on Calvin until Spring 2014.

Since these are not really scholarly resources, it's possibly best to have them in Vyrso (knowing the few footnote links to DBW etc won't work there).
