A woman’s bloodstream has been seeded with death.

An American president must betray his country or sacrifice a woman he loves.

And their only hope lies with a broken man and a desperate gamble.

Curran Hunter almost died at the bottom of the ocean. Now an innocent victim will die unless Hunter can purge her body of deadly devices by piloting the Primus, a prototype submersible the size of a virus. Its control system uses Virtual Reality—its creators assure Hunter there can be no danger.

They are utterly wrong.

Hunter’s every belief will be tested, his very sanity on the line for a woman he doesn’t know.

And to save her life will require the deepest violation of all.

Ride the currents of the inner ocean in a race against time in The Primus Labyrinth!
