The aliens offered food. The price was soldiers. With Earth collapsing and his daughter in need of treatment he cannot afford, paramedic Mark Calder does the unthinkable: he volunteers to fight in an alien war. Ripped from his world and sealed inside a deadly combat frame, Mark is sent to the front lines of a conflict where human troops are treated as expendable assets and survival is little more than a statistical error.

Chase had it all planned out. Do a little time in one of the emperor's jails, say a four-year stretch, for getting rid of some trash that no one would miss, and when he got out, the path to leadership would be wide open. Unfortunately, his bastard of a father, the same one who left his mother to die in poverty and him to run wild on the streets, took an interest. Seeing him sitting on the bench when his case went to court was a shock. But not as big a shock as being sentenced to ten years in the Imperial Navy.

A galaxy-conquering alien armada… …has just knocked on Earth’s door, and it did not come bearing cookies. An unstoppable fleet is busy steamrolling its way across the cosmos, one planet at a time, and humanity is next on the menu. Standing between them and total universal doom is the least likely Avengers lineup ever assembled: a rule-breaking starfighter ace, a stuntwoman who treats gravity like a polite suggestion, a super-assassin with more ways to kill you than you have bones, and a wisecracking alien prankster who thinks reality is his personal toy box. Their job? Protecting not ...

The war for Earth is just the opening act. The Xortaag armada has never lost a war. Now their ships blot out Earth’s sky, and our last line of defense is four people who should absolutely not be in charge of saving the world: A movie-quoting pilot with a death wish. A stuntwoman who treats danger like a hobby. A silent assassin with a body count, not a personality. And a paranoid cosmic spymaster who trusts no one. Their fight starts in Earth’s orbit… then tears through wormholes, broken timelines, and clashing alternate universes. Every choice echoes across multiple Earths in the ...

It is a sentence. Spartan never chose to fight. Dragged into the arenas and forced to survive match after match, he learned to read his enemies, outthink them, and strike ...
