Space Alien War

No one on Earth knows the seeds of the world’s destruction just fell from space. Tiana knows what duty means though. It's why all her friends are dead. Alone on a primitive world. All her all her technology at the bottom of the ocean. Outnumbered by deadly enemies only she can bring to justice. If she fails her mission now, another sentient species will fall. And the Tyrant Empire will rise again - because Earth has just been infected with a fatal parasite.

King Agesilaus and his Terran Legions have won their first victory against the Median Empire. Despite sustaining heavy casualties, they established a vital foothold in enemy territory. Yet the Empire is far from defeated, and they begin to ready their forces for a counterattack. In a display of overwhelming power, they throw fleets of ships and armies of levies and mercenaries against the Terrans. The outcome is uncertain, until Agesilaus and his generals uncover a stunning secret

The Progenitors are here, and Captain Husher knows the galaxy isn’t ready. He spent his entire military career preparing, but it wasn’t enough. As the Interstellar Union continues to flail and colony after colony is consumed, Husher must make some impossible choices. About what to save. And what to let fall to the onslaught. If he can’t find a way to oppose the Progenitors, they will sweep through the multiverse like fire through a parched forest. It all comes down to this.
