Father Knows Best. Of all the kiss-and-tell books about Ronald Reagan, the most unflattering may have been written by the man's own family. Michael Reagan wrote that he found his father neglectful. Patti Davis wrote a novel about a cliche-spouting, befuddled former Governor of California. Now Maureen is weighing in with First Father, First Daughter, a "loving memoir" in which she writes that her half sister Patti did not even know of her existence until Maureen spilled the beans when Patti was eight years old. Her dad's explanation: "Well, we just haven't gotten that far yet." The Reagans say the book is "splendid."
