Race Beneath the Sea: Book 5 in the Changed Course series

By Tony Dunning

Race Beneath the Sea

Britain's secret weapon has changed the course of the Great War.

Commander Godfrey Herbert's manned torpedoes helped force the Ottoman Empire from the conflict, reopen the Dardanelles and restore the vital supply route to Russia. Now the Herbert Programme is expanding at extraordinary speed. New factories are producing underwater Chariots, hundreds of sailors are volunteering to ride them, and a faster generation of machines is already taking shape.

Britain's advantage, however, is no longer secure.

Across the Baltic, German engineers have created Projekt Nixe. Their first prototype is unstable, unreliable and dangerously primitive, yet it proves the impossible can be copied. With every failed dive, Germany learns. With every new machine, the distance between Kiel and Portsmouth grows smaller.

As Thomas Mercer tests a revolutionary rider craft capable of travelling at nearly twice the speed of the earlier enclosed designs, both nations prepare for a new kind of naval war-one fought beneath harbour defences, below minefields and in the darkness under enemy fleets.

The dreadnoughts still command the surface.

The next battles will belong to the men beneath it.

Race Beneath the Sea is the fifth novel in the Changed Course alternate-history series, blending First World War naval action, secret weapons, espionage and a gripping Anglo-German technological arms race.
