Tom McGuire, a retired U.S. Army Military Police colonel and retired local sheriff, is enjoying having his four daughters home for Christmas. Tammy is a Coast Guard Investigative Service special agent; Kelly is a Navy Criminal Investigative Service special agent; Megan is an Army Criminal Investigation Command special agent; and Sarah is an Air Force Office of Special Investigations special agent.
The Secretary of Defense has ordered Tom back to active duty to take command of a terrorism task force investigating a possible nuclear attack on America. Tom has his daughters assigned to the task force, and they learn that the terrorist threat was a hoax.
While conducting the investigation, a riverboat explodes in the middle of the Illinois River and over five hundred people die. Most of those killed were prominent African Americans on a political fundraising cruise. The anti-terrorism investigation and the riverboat explosion become linked, so the task force is now investigating the disaster.
The twists and turns in the breathtaking novel Daddy Six Actual keep Tom and his daughters on edge and in danger. After one daughter is nearly killed, Tom suffers a heart attack, and his daughters are left to finish out the operation. They learn to depend upon each other and their faith even more.
