After a massive volcanic eruption puts earth into nuclear winter, the planet is cloaked in clouds and no sun penetrates. Seas cover most of the land areas except high elevations which exist as islands where the remaining humans have learned to make do with much less. People survive on what they can take from the sea and with foodstuffs supplemented from an orbiting set of space stations.

Jess Drake is an agent for Interforce, a small and exclusive special forces organization that still possesses access to technology. Her job is to protect and serve the citizens of the American continent who are in conflict with those left on the European continent. The struggle for resources is brutal, and when a rogue agent nearly destroys everything, Interforce decides to trust no one. They send Jess a biologically-created agent who has been artificially devised and given knowledge using specialized brain programming techniques.

Instead of the mindless automaton one might expect, Biological Alternative NM-Dev-1 proves to be human and attractive. Against all odds, Jess and the new agent are swept into a relationship neither expected. Can they survive in these strange circumstances? And will they even be able to stay alive in this bleak new world?
