Perfect for you if...

You enjoy psychological thrillers where the protagonist's profession puts them in genuine danger rather than just being incidental to the plot.
You appreciate stories that explore the blurred line between helping people and being harmed by them in return.
You like crime fiction with a medical or psychiatric angle that goes beyond surface-level diagnosis.

Maybe not for you if...

You prefer fast-paced action over internal conflict and character study.
You want escapism rather than stories that dwell on violence and institutional trauma.
You're looking for a standalone thriller rather than book three of a series.

About this book

Psychiatrist David Rothberg works at Vanderkill Prison Hospital, where his dedication to helping troubled patients has earned him both gratitude and enmity. When hostilities escalate into acts of vengeance, David becomes the target in a fight for survival. Inmates driven by an obsessive desire for revenge force David to face the darkest aspects of human nature—in both others and himself.
