Germline (n.) the genetic material contained in a cellular lineage which can be passed to the next generation. Also: secret military program to develop genetically engineered super-soldiers (slang).War is Oscar Wendell's ticket to greatness. A reporter for The Stars and Stripes, he has the only one way pass to the front lines of a brutal war over natural resources buried underneath the icy, mineral rich mountains of Kazakhstan.But war is nothing like he expected... moreGermline (n.) the genetic material contained in a cellular lineage which can be passed to the next generation. Also: secret military program to develop genetically engineered super-soldiers (slang).War is Oscar Wendell's ticket to greatness. A reporter for The Stars and Stripes, he has the only one way pass to the front lines of a brutal war over natural resources buried underneath the icy, mineral rich mountains of Kazakhstan.But war is nothing like he expected. Heavily armored soldiers battle genetically engineered troops hundreds of meters below the surface. The genetics-the germline soldiers-are the key to winning this war, but some inventions can't be un-done. Some technologies can't be put back in the box.Kaz will change everything, not least Oscar himself. Hooked on a dangerous cocktail of adrenaline and drugs, Oscar doesn't find the war, the war finds him. less

Exogene (n.): factor or agent (as a disease-producing organism) from outside the organism or system. Also: classified Russian program to merge proto-humanoids with powered armor systems (slang).Catherine is a soldier. Fast, strong, lethal, she is the ultimate in military technology. She's a monster in the body of an eighteen year old girl. Bred by scientists, grown in vats, indoctrinated by the government, she and her sisters will win this war, no matter the cost.And the costs are high... moreExogene (n.): factor or agent (as a disease-producing organism) from outside the organism or system. Also: classified Russian program to merge proto-humanoids with powered armor systems (slang).Catherine is a soldier. Fast, strong, lethal, she is the ultimate in military technology. She's a monster in the body of an eighteen year old girl. Bred by scientists, grown in vats, indoctrinated by the government, she and her sisters will win this war, no matter the cost.And the costs are high. Their life span is short; as they age they become unstable and they undergo a process called the spoiling. On their eighteenth birthday they are discharged. Lined up and shot like cattle.But the truth is, Catherine and her sisters may not be strictly human, but they're not animals. They can twist their genomes and indoctrinate them to follow the principles of Faith and Death, but they can't shut off the part of them that wants more than war. Catherine may have only known death, but she dreams of life and she will get it at any cost. less

Escaped Germline soldiers need to be cleaned up, and Stan Resnick is the best man for the job. A job that takes him to every dark spot and every rat hole he can find.Operatives from China and Unified Korea are gathering escaped or stolen Russian and American genetics, and there are reports of new biological nightmares: half-human things, bred to live their entire lives encased in powered armor suits... moreEscaped Germline soldiers need to be cleaned up, and Stan Resnick is the best man for the job.
