“With tight pacing, visceral horror, and sharp psychological insight, The Regression Strain explores what happens when science, instinct, and morality collide in the vacuum of survival . . . claustrophobic, haunting, and razor-sharp”
K.C. Finn for Readers’ Favorite
“Kevin Hwang’s debut examines loss, grief, and what it means to be human, all while keeping the reader on the edge of their seat with what might go wrong next. The Regression Strain is a propulsive medical thriller that had me turning pages late into the night.”
USA Today Bestselling Author Kristen Bird
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 something foul is festering under the veneer of leisure. The brig fills with felons, the morgue with bodies, and the vacation becomes a nightmare. Peter and his staff face a vile affliction that pits loved ones against each other and shatters the bonds of civil society. With the ship hurtling towards an unprepared New York, only Peter can neutralize the threat, but he’s hallucinating and delirious.
"Hwang's debut is fast-paced and propulsive, and I loved the medical mystery at the heart of the thriller. He's great at crafting creepy scenes that will stay with you!"
