Grecian's first comic book work, released in 2006, was a collaboration with Canadian comic book artist and illustrator Riley Rossmo on Seven Sons,[1] a graphic novel based on the anonymously written Chinese folktale Ten Brothers known to be written around the time of the Ming Dynasty (1368 to 1644).

In 2013, with fellow creators B. Clay Moore, Jeremy Haun, and Seth Peck, Grecian developed the anthology Bad Karma[4] using a Kickstarter campaign.

Bad Karma is a hardcover comics, prose and art collection featuring five separate, inter-related creator-owned concepts.

The second novel in the series, The Black Country was released in May 2013, then the third, The Devil's Workshop in May 2014, the fourth, The Harvest Man in May 2015, and the fifth, Lost and Gone Forever in May 2016.

In April 2018 Grecian released the stand-alone book The Saint of Wolves and Butchers also published by G. P. Putnam's Sons.
