Because hours had gone by without a new Obama book deal, we now have two more, and the authors couldn’t be more different. President Obama’s half-sister, Maya Soetoro-Ng, will write a children’s book, Ladder to the Moon, based on Obama’s diverse parentage. The other, more predictable author is Bill O’Reilly, who told gossip columnist Cindy Adams that his Obama book would be out in late 2010. “He's becoming a historical figure not because he's black, but because his liberal agenda is taking the country in a direction we've never been before,” O’Reilly said of Obama. Well, it’s original.
