First, you'd have to have up to two years of uninterrupted time. You'd have to have the ability to write. If you don't, you have to hire a collaborator or ghost writer.
Then you have to do research and investigations so your facts are straight. You can't rely on memory. You'd have to hire someone to do that if you don't have the time and resources to do it yourself.
Then you'd have to hire an attorney to review your book so you don't get sued. Then you have the daunting and sometimes impossible task of finding a publisher who deems the book marketable.
Then if it does get published, you sit and pray it sells. If it doesn't, all your investments are down the drain.
Perhaps a book is in her future, but the farther away the book would be from the events, the less it will sell.
If it was so easy to write and sell a book, we scribes here at FR would all be millionaires.
