A bestseller in the US and the UK, Geoff’s debut novel Undersea is available on Amazon in paperback, or on Kindle. The long awaited sequel, Undersea Atrophia is available on Kindle and in paperback as well.


In a world flooded and irradiated by a nearly forgotten cataclysm from generations passed, all that remains of civilization clings to life in two war-torn, city-sized submarines. For fifty years, the only peace between them had come from separation.

Now, young council woman Ralla Gattley has uncovered mysteries that will bring these two factions face-to-face, initiating a series of events that will forever change their undersea world. She didn’t expect to meet Thom Vargas, a bored fisherman and aspiring drunk who merely wants to climb one rung on the social ladder. Little did he know that single step may well put the fate of the world in his hands.


A great silence has settled upon a drowned world. In the final battle of their final war, the massive citysubs Universalis and Population reduced each other to ruins. One lays wrecked on the seafloor. The other, beached and lifeless, litters the island of pristine polar ice it tried to destroy.

Pockets of survivors huddle together. On the frigid surface, Ralla Gattley and Thom Vargas cling to life and each other. Below, the soldier Geran Lo fights relentlessly to free trapped and drowning civilians.

As they struggle against a world determined to kill them, a new and even more dangerous menace approaches.
