Nobody’s safe when the inner beast awakens...

Dr. Peter Palma joins the medical team of the Paradise to treat passengers for minor ailments as the cruise ship sails across the Atlantic. But he soon discovers that something foul is festering under the veneer of leisure. Deep in the bowels of the ship, a vile affliction pits loved ones against each other and shatters the bonds of civil society. The brig fills with felons, the morgue with bodies, and the vacation becomes a nightmare.

One by one, the chaos claims Peter's allies. His mentor spirals into madness and the security chief fights a losing battle against anarchy. No help comes from the captain, who has an ego bigger than the ocean.

With the ship racing toward an unprepared New York, the fate of humanity hinges on Peter's deteriorating judgment. But he's hallucinating and delirious...and sometimes primal urges are impossible to resist.

The Regression Strain is a fast-paced medical thriller laced with psychological suspense, perfect for fans of Michael Crichton and Blake Crouch.
