A good ghostwriter might try her best to help you avoid writing an embarrassing memoir. She will steer you away from whining, from banal revelations and anecdotes that don't land the way you think they land. The best kind of ghostwriter for a royal would massage the book to be as mysterious, charitable, and high-minded as possible--in the royal's ultimate best interest.
If she can help it, she won't let you tell about losing your virginity unless it was with a now dead fellow virgin who you went on to marry or at least love deeply and the whole point of the story is to illustrate the depth of your love and the preordained nature of your tragic union.
She might suggest you title your memoir "In Line" or "Harry's Heart" and fill it with perceptive yet glowing portraits of all your relatives and associates, a veritable love letter, an unexpected gift. Insights and scenes nobody had access to before (Charles tenderly ministering to a servant's cut hand, Camilla cooking eggs over a campfire, Kate and William tickling their toddlers during a thunderstorm, Megan doing her taxes with a furrowed brow at her kitchen table, the Queen quietly weeping as she watches a news report about Syria—that kind of thing) that fill the reader with a general glow of sympathy and affection.
THEN see how the world treats you, ya big baby.
