About the Author

Mark Z. Harrondale writes speculative fiction that explores identity, power, and human connection across imagined futures and fantastical worlds. His debut novel examines the cost of safety in a world governed by artificial superintelligence.

Born and raised in Serbia, he came of age during the peak of dystopian and fantasy fiction—an influence that shaped both his imagination and his approach to storytelling. Those formative years became the foundation for The Symbiosis Series.

At twenty-nine, he made himself a promise: for once in his life, he would finish what he started. After years of abandoned projects and half-pursued interests, Salvation became the first thing he ever saw through to the end—a test of will as much as craft. The manuscript took shape across six continents, in the margins of a life spent observing cities, cultures, and the thousand small ways people adapt to survive.

He's currently working on Book Two.
