Presumably his mum and dad took some part in the process, somehow.
Having written since he was a wee nipper, he embarked on his first published mega-project, the ongoing and growing Cynos Union series, a project that's both a love letter to, and a reimagining of, the space opera stories in which he absorbed himself while growing up. Throughout his whole life, Mark knew he wanted to write; he wanted to tell stories, to reach into people's heads, and let them experience the vastness and wonder of the universe in the same way that he experiences it. Armed only with a media degree he's never found a use for and a keyboard that he's convinced is becoming self-aware, his mission is to bring you all along into his huge, weird, and often twisted universe.
Mark often says that writing is like playing god in his own personal universe, albeit without any real responsibility over actual people.
He fervently believes this is probably for the best.
