In the heart of London lies the Engine Ward, a district forged in coal and steam, where the great Engineering Sects vie for ultimate control of the country. For many, the Ward is a forbidding, desolate place, but for Nicholas Thorne, the Ward is a refuge. He has returned to London under a cloud of shadow to work for his childhood friend, the engineer Isambard Kingdom Brunel. Deep in the Ward's bowels, Nicholas can finally escape his strange affliction – the thoughts of animals that crowd his head. But seeing Brunel interact with his mechanical creations, Nicholas is increasingly concerned that his friend may be succumbing to the allure of his growing power. That power isn't easily cast aside, and the people of London need Brunel to protect the streets from the prehistoric monsters that roam the city. King George III has approved Brunel's ambitious plan to erect a Wall that would shut out the swamp dragons and protect the city. But in secret, the King cultivates an army of Sunken: men twisted into flesh-eating monsters by a thirst for blood and lead. Only Nicholas and Brunel suspect that something is wrong, that the Wall might play into a more sinister purpose—to keep the people of London trapped inside.

A new iron curse threatens London Now that the Sunken have been defeated, Isambard Kingdom Brunel can begin the task of making the British Empire great once more. All that stands in his way are the French forces closing in on the country, and rival engineer Robert Stephenson, who seeks to undermine Brunel's power by disobeying his orders at every turn. Nicholas Thorne once again finds himself caught in the middle of a war he does not believe in. Only now, Nicholas is assailed every waking hour by terrible voices – animals in excruciating pain pound against his skull, begging for release. Can Nicholas fight through the pain and retain control of his mind to protect the people he loves? Not content to lay idle while his empire is attacked and civil war looms, Brunel has one last great innovation to unveil. This new machine could be the salvation of England, or the destruction of them all. The Gauge War is the second book in S C Green's Engine Ward series, exploring the clash of science and religion in an alternatee history London where dinosaurs still survive.

Forced from London after the death of Brunel, Thorn and her people – the Stokers – reside in the Graveyard; a wasted landscape of scrap metal and disused railway carriages. Shunned by her own people for her family's part in their exile, Thorn's skill with animals is the only thing saving her from banishment. With her friend Lurgo, she hunts the great tri-horned monsters in the surrounding swamps, desperately trying to keep control of her strange power and restore her family's soiled name. Now Brunel's old Wall is moving again, expanding over the English countryside. And with it comes a horror that should have been long dead – once human creatures turned maniacal by a diet of lead and soot. The Stokers propose a suicide mission, a last-ditch effort to reclaim their home – sending Thorn into the Wall to die; an expendable distraction to ensure their own survival. But Thorn has other ideas. Together with Lurgo, a blind adventurer, an eccentric menagerie proprietor and a tame triceratops, she sets out to stop the new threat. In a world dominated by powerful men and fierce mechanical monsters, can one woman triumph where so many have failed? Thorn is the third and final volume in the Engine Ward dark fantasy series by S C Green.
