My recommendations were based on books I have actually read. (Although it is possible to have a (sort of) opinion on a book without actually having read it-- see Whit Stillman's Tom Townsend as my favorite example in the charming and brilliant Metropolitan.* Do I see a summer movie recommendation post coming??).
So here are the books I am reading (or re-reading) this summer, time, energy, and discipline permitting:
Rosemary Sutcliff, Sword at Sunset
Dietrich Bonhoeffer, Life Together
Alan Fadling, An Unhurried Life: Following Jesus' Rhythms of Work and Rest
Siegfried Wenzel, The Sin of Sloth: Acedia in Medieval Thought and Literature
P.G. Woodhouse, My Man Jeeves
Also on the short list, but unlikely:
Dave Kraft, Leaders that Last
Jim Belcher, Deep Church
Ruth Haley Barton, Pursuing God's Will Together
*Metropolitan is a clean and virtuous movie, but topics of discussion in the movie make it suitable for adults only, IMO. Likewise Buechner's book Godric from yesterday's list.
