The Michael Kay Series

Beyond the Horizon

Horizon's Edge

1958. Peace is fragile, and the next arms race is moving into space. Asked to build a system he no longer believes in, Kay forms a dangerous alliance across enemy lines to stop a catastrophe before machines and mistrust decide humanity's fate.

Horizon's Divide

About the Author

Joe Koshuta is a software executive with more than twenty-five years of experience in product development and emerging technologies. His work has focused on how complex technical systems are designed, deployed, and shaped by the organizations that use them.

That experience directly informs the Michael Kay series, which explores how scientific breakthroughs and strategic technologies ripple through governments, wars, and individual lives. These novels reflect a long-standing interest in the gap between what technology is designed to do and what the world ultimately does with it.

He lives in the United States and continues to write historical thrillers that sit at the intersection of science, power, and consequence.
