He Might Be Still On Mars is a thriller set in the latter years of the 26th Century. Mankind has spread out into the rocky planets of the Solar System and the rocky moons of the Gas Giants such as Jupiter and Saturn. Despite light speed and near light speed travel, the number of people emigrating to these new worlds is in the doldrums.

This lack of enthusiasm is driven primarily by the savagery of raids by pirate chief, Wilson Black. Powerful politician and scientist, Stella Ling, sends Owen Bone and his Synthetic partner Sandi Shaw on a manhunt for an absconded husband, Freddie Ling. This is camouflage for a plan to eliminate Wilson Black. Owen and Sandi are subject to terrifying injuries and stresses that test what it means to be human and Synth. In overcoming these challenges, they find help in the most unlikely places, leading to a showdown with Black in the frozen remote taiga forest of Siberia.
