Series background & context
The Union of Stars books sit in D.L. Harrison's bigger science fiction side. They begin with Captain Dane Johnson, a fleet officer tied to New America, and throw him into a future shaped by military pressure, alien threats, and the need for humanity to hold together when things start breaking apart.
The titles tell you a lot about the shape of the series. Humanity's Champion starts on a personal level, with Dane carrying the burden of action and leadership. The Iv'ax Incursion widens the threat into open conflict. Union of Stars points toward the larger political and strategic problem, how do separate powers survive long enough to become a true alliance. That makes the series a mix of military science fiction and big-picture space politics.
If you like future-war stories that stay centered on one capable lead while the stakes keep expanding, this is the kind of read you are getting here.
