Angles of Attack
The alien forces known as the Lankies are gathering on the solar system’s edge, consolidating their conquest of Mars and setting their sights on Earth. The far-off colony of New Svalbard, cut off from the rest of the galaxy by the Lanky blockade, teeters on the verge of starvation and collapse. The forces of the two Earth alliances have won minor skirmishes but are in danger of losing the war. For battle-weary staff sergeant Andrew Grayson and the ragged forces of the North American Commonwealth, the fight for survival is entering a catastrophic new phase.
Forging an uneasy alliance with their Sino-Russian enemies, the NAC launches a hybrid task force on a long shot: a stealth mission to breach the Lanky blockade and reestablish supply lines with Earth. Plunging into combat against a merciless alien species that outguns, outmaneuvers, and outfights them at every turn, Andrew and his fellow troopers could end up cornered on their home turf, with no way out and no hope for reinforcement. And this time, the struggle for humanity’s future can only end in either victory or annihilation.

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.
