"Shattered by grief and dreaming of vengeance, Penn Cage sees his world collapsing around him. The woman he loves is gone, his principles have been irrevocably compromised, and his father, Dr. Tom Cage, once a pillar of the community, is about to be tried for the murder of a former lover. Most terrifying to all, Dr. Cage seems bent on self-destruction and has frozen Penn out of the trial, preferring to risk dying in prison to revealing the truth to his son. For decades Dr. Tom Cage has had a second son known to almost no one, the product of an affair with his African-American nurse, Viola Turner. It is this bitter son--Penn's half brother--who set in motion the case against Dr. Cage. But a murder charge may be the least of Tom's worries. In the 1960s South, Viola Turner became a nexus point between Penn's father and the Double Eagle group, a savage splinter cell of the KKK. Now, led by the psychopath Snake Knox, the surviving Double Eagles will stop at nothing to keep their past deeds buried, and they mean to ensure that Dr. Cage either takes the fall for them or takes his secrets to an early grave. Unable to trust anyone--not even his own mother--Penn joins forces with Serenity Butler, a writer investigating his father's case. Together, Penn and Serenity, a former soldier, desperately battle to crack the Double Eagle group and discover the secret history of both the Cage family and the South itself, risking the only thing they have left to gamble: their lives.--Publisher description.
