NEW YORK -- Another Obama relative has a book deal. 

A memoir by George Obama, the president's half brother and a resident of Huruma, Kenya, will be published by Simon & Schuster in January 2010. George Obama, 27, shares the same father with his famous, older half sibling, although George and Barack Obama -- 20 years apart in age -- did not grow up together and did not meet as children. 

George is the youngest of the senior Obama's seven children and was born six months before his father died. 

Little is known about George Obama. The book, tentatively titled "Homeland" and to be written with author-journalist Damien Lewis, will tell of George Obama's fall into crime and poverty as a teenager and his eventual embrace of community organizing -- a passion shared by the president -- and of advocacy for the poor, an identification so strong that he chooses to live among them. 

"Even had George Obama not been our President's half brother, his story is moving and inspirational," David Rosenthal, Simon & Schuster publisher and executive vice president, said in a statement Sunday. "It is an object lesson in survival, selflessness and courage." 

Financial terms were not disclosed, but an official with knowledge of the negotiations said the deal was worth six figures. The official, who was not authorized to discuss the contract, spoke on condition of anonymity. 

Other Obama relatives are working on books, including a half sister, Maya Soetoro-Ng; and the brother of first lady Michelle Obama, Craig Robinson. Duke University Press is releasing the doctoral dissertation of the president's mother, Stanley Ann Dunham, who died in 1995. 

Barack Obama has written a pair of million-selling books, "The Audacity of Hope" and "Dreams from My Father," in which he describes George Obama as "a handsome, roundheaded boy with a wary gaze."
