In 2067, Major Dean "Duke" Rearden made a decision that haunted him for the rest of his life. When his elite lunar squad discovered an alien settlement and first contact turned violent, Duke's grief became rage and rage became massacre. Twenty-three aliens died, including children. Command buried the truth. The squad scattered. Duke tried to forget. The aliens didn't. Five years later, they came for justice.

One by one, Duke's former squad was hunted down. Only Duke escaped, spending decades running with his family, always looking over his shoulder, never staying anywhere long enough to call it home. Now seventy-two and beginning to believe he's finally safe, Duke agrees to a family cruise to Jupiter. He's wrong about being safe. He's wrong about everything. The aliens don't want his death. Death would be too easy. They want him to suffer as their people suffered¿to build families and lose them, over and over, until the scales are balanced.

His nine-year-old grandson witnesses it all. And he's the only one who remembers. The cycle has begun. Twenty-three deaths remain. GRANDPA 777 - Book One of the 777 Series.
