By definition, a sub-species is a group within a species that has become somewhat different physically and genetically from the rest of the species. The Deep Water Corporation created in secret a sub-species of human to mine lithium and other precious ores from the ocean floor. They didn’t name them; they’re not important enough for a name. They are company slave labour, disposable assets in the race to strip-mine the ocean floor.

At least they were, until something or someone started fighting back. After an underwater uprising that included the kidnapping of one CEO’s daughter, the company must take steps. Gabriel Lawson, a skilled mercenary, has been hired for the search and rescue mission, with only the general requirement to keep a body count.

Follow Gabriel as he dives deep into a world where human experimentation is normal, and where the ocean can turn slaves into her champions.
