In the name of honor by Richard North Patterson

The McCarran and the Gallaghers, two military families, have been close for decades, ever since Anthony McCarran and his friend Jack Gallaghers went to Vietnam and only Anthony came back. Anthony's wife committed suicide when their children are young. So the rest of the families become a family unit of their own with Gallagher's daughter Kate and McCarran two children Meg and Brian. Tragedy strikes when Brian shoots and kills D'Abruzzo, who is married to Kate and his commanding officer in Iraq. Captain Paul Terry, who is about to leave the service, is appointed to defend Brian. As the trial goes on, Paul must find out what really happen that fateful night. There are many twist and turns, especially at the very end. It's worth reading. Pat M
