Michelle Obama's Brother to Pen Book

First Lady Michelle Obama's brother is working on a book which, he says, is part tribute to his family and part inspirational guide.

Craig Robinson's book, A Game of Character, will be published next year by Gotham Books. In a statement issued Thursday, Robinson said, "I've been privileged to know some extraordinary people in my life. I've watched as my sister, Michelle, a rock of a mother, became a leader in her own right. My brother-in-law, President Barack Obama, who I knew from the first time I met him had something special, continues to inspire all of us."

Robinson, who coaches men's basketball at Oregon State University, introduced his sister last summer at the Democratic National Convention in Denver.
