Humankind may have won the battle, but a new threat looms larger than ever before...
Earth’s armed forces have stopped the Lanky advance and chased their ships out of the solar system, but for CDC officer Andrew Grayson, the war feels anything but won. On Mars, the grinding duty of flushing out the twenty-meter-tall alien invaders from their burrows underground is wearing down troops and equipment at an alarming rate. And for the remaining extrasolar colonies, the threat of a Lanky attack is ever present.
Earth’s game changer? New advanced ships and weapons, designed to hunt and kill Lankies and place humanity’s militaries on equal footing with their formidable foes. Andrew and his wife, Halley, both now burdened with command responsibilities and in charge of more lives than just their own, are once again in humanity’s vanguard as they prepare for this new phase in the war. But the Lankies have their own agenda... and in war, the enemy doesn’t usually wait until you are prepared. As Andrew is once again plunged into the chaos and violence of war with an unyielding species, he is forced to confront the toll this endless conflict is taking on them all, and the high price of survival... at any cost.

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.
