Two sisters. One dark secret. One dead patient. A doctor racing to survive.

As chief surgical resident at Lexinbridge Regional Hospital, Dr. Zora Smyth has survived kidnapping, jail time, and threats at gunpoint. With her long-missing sister Alisa finally back in her life and her romance with police lieutenant Dave McKesson rekindled, Zora is focused on her upcoming board exams—and keeping her patients alive.

But when a routine surgery turns deadly and a patient dies on her table, Zora demands answers.

As the case spirals into a malpractice lawsuit that threatens to destroy her career—and as strange attacks target those closest to her—Zora races against time to uncover the truth before she loses everything.

Yet Alisa harbors a chilling secret: Dave isn't who he claims to be. She's certain he has ties to the mob, and she's determined to protect Zora, even if it means launching a covert investigation of her own.

In this high-stakes thriller, where medicine, law, and organized crime collide, Zora must confront the terrifying possibility that everything she's fought for—her career, her love, her family—could unravel in an instant.

As the clock ticks down, can Zora uncover the truth before the past destroys them all?
