The Astonishing Life of Octavian Nothing: Traitor to the Nation by M.T. Anderson.

In pre-Revolutionary America, Octavian and his mother Cassiopeia live in luxury on a grand estate. Octavian, a brilliant child, is receiving a classical education where he is taught to observe, reflect, and draw rational conclusions about the world around him. But then in one horrible moment, he discovers that his upbringing has been an experiment to prove the inferiority of blacks to whites - and thus to encourage the continuation of slavery.

This is not an easy read. Octavian narrates the book in an 18th century style that may be off-putting to some. However, it is a powerful story where you feel Octavian's rage and pain as he observes the hypocrisy of those who purport rational thought and free will but only do so as it fits their own motives.
