COMING SOON—a Saunders and Walsh suspense thriller

2027

Book cover for Dark Water by Harry Black, showing a moonlit Arctic fjord beneath the northern lights with a submarine moving through the water.

In the remote Arctic wilderness, a British black ops mission spirals into chaos. Beneath a decaying Cold War outpost lies Project 627-K, a lost experimental submarine powered by a volatile new technology. As global tensions mount, a rogue American sub shadows the ice, and an ex–Soviet spymaster clutches a detonator that could set the world alight. Dark Water is a blistering thriller of espionage, sacrifice and the high price of keeping secrets buried.
