Hilary Lifton is not one to boast, and I write that with more understatement than you can imagine.I was introduced to her recently at a party by someone who said she was a big ghostwriter. When I asked her about her career, she mentioned working on a self-help book.It was only when I Googled her later that I learned she has written 16 New York Times bestsellers and is one of the most sought-after ghostwriters alive. (While she chooses not to name her bold-faced clients, you can find out who some of them are by going to her site.)I've never had such an interesting conversation about ghostwriting and I challenge you that you've probably not heard one. I know that's setting expectations quite high but I'm ready to meet them!
