Marko Kloos is a novelist, freelance writer, and unpaid manservant to two small children. He is a graduate of the Viable Paradise SF/F Writers' Workshop.

Marko writes primarily science fiction and fantasy. He has been getting his genre fix at the library ever since he was old enough for his first library card. In the past, he has been a soldier, a bookseller, a freight dock worker, a tech support drone, and a corporate IT administrator.

Born and raised in Germany, Marko now lives in New Hampshire with his wife and two children. Their compound, Castle Frostbite, is patrolled by a roving pack of dachshunds.
