Marko Kloos was born and raised in Germany, in and around the city of Münster. In the past, he has been a soldier, bookseller, freight dock worker, and corporate IT administrator before he decided that he wasn't cut out for anything other than making stuff up for a living.

Marko writes primarily science fiction and fantasy, his first genre love ever since his youth when he spent his allowance mostly on German SF pulp serials. He likes bookstores, kind people, October in New England, Scotch, and long walks on the beach with Scotch.

Marko lives in New Hampshire with his wife, two children, and roving pack of vicious dachshunds.
