On November 1st, 1916, nine-hundred men of the 13th Battalion of The Pennine Fusiliers vanished without trace from the battlefield, only to find themselves stranded on an alien planet. There they must learn to survive in a frightening and hostile environment, forced to rely on dwindling supplies of ammo and rations as the natives of this strange new world begin to take an interest. However, the aliens amongst them are only the first of their worries, as a sinister and arcane threat begins to take hold from within their own ranks!

The Iron God! Three months after the Pennine Fusiliers vanished from the Somme and found themselves stranded on an alien world, Corporal ‘Only’ Atkins and his Black Hang Gang are sent to track down the HMLS Ivanhoe, the Battalion’s tank, currently exploring the wilderness and days overdue. The encampment is coming under attack by the alien Khungarrii, and the tank may be their only hope for a decisive victory. Fighting for their lives against the mounting horrors of No Man’s World, Atkins and his men – and their alien prisoner – uncover an abandoned edifice, and a terrible secret. They must bring their discovery, and the tank, back to the base, but their only hope for survival – and a way home – lie in the psychotropic fuel-addicted crew of the Ivanhoe... and its increasingly insane commander!
