Lower Rhumbsford is a city far removed from its glory days. On the banks of the great River Rhumb, its founding fathers channelled the river's mighty flow into a subterranean labyrinth of pipes, valves and sluices, a feat of hydraulic prowess that would come to power an empire. But a thousand years have passed since then, and something is wrong: the pipes are leaking, the valves stuck, the sluices silted, and the once-torrential Rhumb has been reduced to a sluggish trickle.

The fortunes of the Locke family, descendants of the city's most celebrated engineer, are similarly reduced. In a once-fashionable quarter of the once-great city, siblings Samuel and Briony Locke are about to be drawn into a web of ancestral secrets and imperial intrigues, as a ruthless new power arises...

Reviews for A Clockwork River:

'Exuberant isn't often a word you'd apply to fantasy novels, but A Clockwork River rushes along at a pace to match the waterway at its heart' SFX

'Delightfully weird and clever' Grimdark Magazine

'Oh, just plunge into this "hydro-punk" fantasy novel, will you' The Times

J.S. Emery is a brother-sister writing team, born in North Idaho into a homeschooling family of seven children, each of whom received an air rifle and a copy of The Odyssey by way of a fifth birthday present. This background prepared them wonderfully for writing fantasy novels but very poorly for formal education. After dropping out of secondary school, they worked jobs including ballet dancer, emergency room janitor, and map librarian in various parts of Europe and North America. They now live in the United States, where they are godparents (and, increasingly, dungeon masters) to one another's children.
