On the Moon and Mars, humanity scrapes forward while a ruined Earth sits contested between shadow corporations and a corrupt Galactic Government. Daniel Hunt—deadliest fighter anyone has ever seen, unsure whether he's even fully human—wakes from amnesia knowing only his name. A mysterious offer to infiltrate Earth for clues about his past sets him on a path that will ripple across twelve books and bring him face to face with alien threats, ancient Relics, and the truth of the Pack Protocol.

Daniel Hunt is a supremely capable, quietly philosophical soldier whose enhanced healing and combat skills are matched by an earnest sense of justice. He resists leadership but repeatedly steps up when the galaxy needs it, and his loyalty to those he calls family is his defining trait. His dry humor and the camaraderie of the Pack make him easy to root for across a lengthy twelve-volume run.

Across twelve books, Daniel's personal quest for identity expands into a galaxy-wide war: first against the alien Voy invasion of Mars, then a hunt for three ancient Relics, then a war against a dimension-crossing darkness called the Darkening, and finally against a corrupt galactic government. Each phase adds new allies to his 'Pack'—a found family of soldiers, aliens, and AIs—and the series rewards long-haul readers with consistent payoffs for every planted seed.
