Chains of Command
The assault on Earth was thwarted by the destruction of the aliens’ seed ship, but with Mars still under Lanky control, survivors work frantically to rebuild fighting capacity and shore up planetary defenses. Platoon sergeant Andrew Grayson must crash-course train new volunteers — all while dulling his searing memories of battle with alcohol and meds.
Knowing Earth’s uneasy respite won’t last, the North American Commonwealth and their Sino-Russian allies hurtle toward two dangerous options: hit the Lanky forces on Mars or go after deserters who stole a fleet of invaluable warships critical to winning the war. Assigned to a small special ops recon mission to scout out the renegades’ stronghold on a distant moon, Grayson and his wife, dropship pilot Halley, again find themselves headed for the crucible of combat — and a shattering new campaign in the war for humanity’s future.

Marko Kloos
Marko Kloos has built a reputation in the world of military science fiction by weaving complex narratives where war, politics, and the human condition collide against the backdrop of interstellar conflict. A writer whose career is as multifaceted as his stories, Kloos' journey from his native Germany to the United States is one of both personal reinvention and creative discovery.
Growing up in the small town of Münster, Germany, Kloos developed an early love for science fiction, delving into the works of authors who would later inspire his own storytelling. His first passion, however, wasn't writing—it was military service. He spent time as a junior NCO in the West German military, which would later seep into his stories, giving them a grounded, authentic touch. After the military, Kloos tried his hand at several professions, including bookselling and IT administration, before settling into life as a full-time writer.
