Troy Rising Series by John Ringo (Books 1 to 3)

Book 1: First Contact Was Friendly
When aliens trundled a gate to other worlds into the solar system, the world reacted with awe, hope and fear. But the first aliens to come through, the Glatun, were peaceful traders and the world breathed a sigh of relief.


Who Controls the Orbitals, Controls the World
When the Horvath came through, they announced their ownership by dropping rocks on three cities and gutting them. Since then, they've held Terra as their own personal fiefdom. With their control of the orbitals, there's no way to win and earth's governments have accepted the status quo.

Live Free or Die.
To free the world from the grip of the Horvath is going to take an unlikely hero. A hero unwilling to back down to alien or human governments, unwilling to live in slavery and with enough hubris, if not stature, to think he can win. Fortunately, there's Tyler Vernon. And he has bigger plans than just getting rid of the Horvath.
