WTF? Didn't Bruni author it?
All celebrity books are ghost written. Obama, Rush, Governor Palin, Hillary! all used ghost writers. Google ghost writing some time. It's great business if you can write and control your own ego.
Dude, somehow I've landed in a universe where a Kenyan Communist is in charge of America, and Islam is called the "religion of peace".
Do not ask me how things work here.
