Penn Cage is caught in the darkest maelstrom of his life. The death of his father's African-American nurse has fractured Penn's family and turned Dr. Tom Cage into a fugitive. Penn has inadvertently started a war with an offshoot of the KKK called the Double Eagles, and Penn's fiancee, journalist Caitlin Masters, is chasing the biggest story of her career. Both Caitlin and the Feds that Penn reluctantly teams up with believe Tom can lead them to evidence of America's most secret, shameful history, a time when powerful men committed violent race murders to conceal a conspiracy involving the Mafia, the Double Eagles, and the assassination of JFK. In the end, all roads lead to the Bone Tree, a legendary killing site that may conceal far more than the remains of the forgotten.
