THE REGRESSION STRAIN

by Kevin Hwang

September 15 – October 10, 2025 Virtual Book Tour

Synopsis:

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 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.

Praise for The Regression Strain:

“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

“I am very impressed with Hwang’s first novel. He has an ability to draw in his reader within the first few pages. There were some unexpected twists and heartwarming moments. I look forward to reading more by this author.”
~ Amazon reader

“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!”
~ Amazon reader

“I really enjoyed this novel. I was hooked from the beginning, wanting to know more about the mysterious illness and the troubled backstory of Peter, a doctor grappling with his past whilst trying to have a fresh start in life with a new job on a cruise ship. The author Kevin Hwang portrays Peter with such realism and empathy. Hwang’s keen eye for people’s inner monologue and perspective on their secret struggles must be informed by his years of work as an internist. Ultimately, Hwang’s story is a fast-paced thriller that reveals the darker side of human nature lurking in all of us. I had trouble putting this book down and can’t wait to read his next novel!”
~ Amazon reader

“This is an excellent thriller, with plenty of plot twists and turns that kept me guessing. It packed plenty of excitement and intrigue with excellent medical knowledge from the author. You don’t want to put this down until you’ve finished reading.”
