Query: A great book detailing the frustrations of black males.

Nathan McCall has written a awesome book detailing the frustrations of being black and male in the 1970s and much of what he felt then, is the same frustrations that our males are still faced with in today's society. McCall givesmore than enough realism as he depicts his life from the oldNathan to becoming the new Nathan. It is indeed a challenge and through the book he keeps hope alive and tries to do the right thing.
