"drive bys"

Yesterday we saw a couple of "drive-by" healings - O.K, so we weren't in the car, but as we were leaving this bookstore, I asked the manager why she hadn't read any of the books of a particular author writing about supernatural Christianity. She carried a few titles, but hadn't read any. She acted a bit embarrassed (probably because I'd talked with her so much about his stuff previously). Anyway, at that moment, a word of knowledge comes (lower abdomen on the side). Both she and her friend have pain in that area - my wife laid her hands on each of them, and the pain left! I said, "We learned that from one of the books you haven't read yet"! Then she asks, "Which one of his books should I start with"?
