Book 1

Aftershocks

by Marko Kloos

Published 1 July 2019

“A new series that promises to be just as engrossing [as Frontlines]…the action just as exciting, the science just as solid, the tension just as high. I gulped down the first book in a day, and I am already eager for the next one.” ―George R. R. Martin

Across the six-planet expanse of the Gaia system, the Earthlike Gretia struggles to stabilize in the wake of an interplanetary war. Amid an uneasy alliance to maintain economies, resources, and populations, Aden Robertson reemerges. After devoting twelve years of his life to the reviled losing side, with the blood of half a million casualties on his hands, Aden is looking for a way to move on. He’s not the only one.

A naval officer has borne witness to inconceivable attacks on a salvaged fleet. A sergeant with the occupation forces is treading increasingly hostile ground. And a young woman, thrust into responsibility as vice president of her family’s raw materials empire, faces a threat she never anticipated.

Now, on the cusp of an explosive and wide-reaching insurrection, Aden plunges once again into the brutal life he longed to forget. He’s been on the wrong side of war before. But this time, the new enemy has yet to reveal themselves…or their dangerous endgame.


Book 2

Ballistic

by Marko Kloos

Published 26 May 2020

“I gulped down Ballistic in one long read, staying awake half the night, and now I want the next one!” ―George R. R. Martin

There is a personal price to pay for having aligned with the wrong side in a reckless war. For Aden Jansen it’s the need to adopt a new identity while keeping his past hidden. Now he’s integrated himself aboard the Zephyr, a merchant ship smuggling critical goods through dangerous space. But danger is imminent on planet Gretia, as well. Under occupation, torn between postwar reformers and loyalists, it’s a polestar for civil unrest.

Meanwhile an occupation forces officer is pulled right back into the fray when the battle alarm is raised, an ambitious heiress is entangled in a subversive political conspiracy, and an Allied captain is about to meet the enemy head-on.

As Aden discovers, the insurgents on Gretia―and in space―are connected, organized, and ready to break into full-scale rebellion. History is threatening to repeat itself. It’s time that Aden rediscovers who he is, whom he can trust, and what he must fight for now.


Book 3

Citadel

by Marko Kloos

Published 10 August 2021

An interplanetary battle is renewed in an epic novel of a warring solar system by the author of Ballistic.

The war should have been over. But it’s not for a group of nationalists grabbing for control.

It’s been two weeks since a missile with a nuclear warhead tore through the planetary defenses in the most blistering large-scale attack ever committed in the history of the Gaia system. Commander Dunstan Park of the Rhodian navy has been handpicked to command an experimental cruiser that could dictate the course of the escalating conflict. All he has to do is keep the ship from falling into the wrong hands.

On Gretia, the powder keg is beyond control. A terrorist attack against civilians draws Idina Chaudhary into a costly battle. It also forces a cautious Aden Jansen back into the fray. Now dedicated to a just cause, he’s still keeping his past hidden. The risk of exposing his former alliance could twist not only his fate but also that of his sister, Solveig, heir to the family empire.

With no time to waste, Dunstan hits the ground running. But as insurgents threaten the unstable peace, what’s ahead for both sides could change the destiny of the Gaia system forever.
