You know how I said the other day that I’d never heard of a book that Jonathan Yardley said “may well be the best baseball book ever”? Here’s another I’d missed: Charla Muller’s 365 Nights: A Memoir of Intimacy (Berkley, 288 pp., $14, paperback), the #2 bestseller in the “Love & Romance” category on Amazon. It comes from a woman who promised her husband sex every night for a year for his 40th birthday, and if the comments on Amazon are right, Muller left out all the good parts. A reader-reviewer complained: “The author uses the premise to discuss almost everything except sex. There are almost no details about the sex-life of the author and her husband.” But Muller has started offering a free Bible study guide to the book.
