Dr. Zora Smyth has only one choice: fight back—or end up dead.

Zora's world shatters in an instant.

One moment, she's a brilliant chief surgical resident with a promising future. The next, she's dragged from her home in handcuffs—accused of murdering her former mentor.

She's been framed.

By someone powerful.

Someone who knows exactly how to destroy her: strip away her reputation, revoke her license, and leave her to rot behind bars.

Trapped in a jail where danger lurks in every shadow and even the guards can't be trusted, Zora races to clear her name, preserve her sanity, and survive long enough to expose the truth. But her enemy is always one step ahead—ruthless, relentless, and obsessed with watching her fall.

Can Zora beat the system—and a faceless enemy—or will she lose everything she's worked so hard for, including her life?

LETHAL OBSESSION is the third book in Dobi Cross's twist-filled medical thriller series—perfect for fans of strong female leads, high-stakes suspense, and thrillers that keep you guessing until the very end.
