A few nights back, we thought all the kids were asleep, only to discover Penny under our covers, reading Love and Salt: A Spiritual Friendship through Letters, written back and forth over the years by Amy Andrews and Jessica Griffith. "This is a cool book," she told me. And although I'm certain the only reason Penny thought it was cool is because she loves reading any correspondence between two people (I routinely discover her reading through my text messages and emails), I nevertheless concur. For anyone who enjoys honest theological conversation, memoir, and just plain good writing, I highly recommend this book.
