Definitely a good read. In fact, I want to read it again...there's a certain 'mood' to it that's slightly addictive. A well-crafted denouement as well. I do wonder what MacKenzie will do next.

Unlawful Harvest

A Gripping Medical Thriller That’ll Keep You Up at Night

Unlawful Harvest is a Kenzie Kirsch Medical Thriller. If you have been reading the Zachary Goldman Mysteries, then you have met Kenzie Kirsch, who works in the medical examiner’s office. 

Kenzie Kirsch had led a sheltered life; daughter of a wealthy lobbyist, her way had been paved for her, and she wasn’t really required to do much in life. There were events to make an appearance at, boards to sit on, fundraisers to support, but she could pick and choose what she wanted to do and how busy she wanted to be. 

Until her sister’s death exposes her to a world of medical corruption and moral ambiguity.

As Kenzie begins to question what really happened, she discovers that finding the truth may cost her everything—and she’s not the same woman she was when this journey began.

If you’re drawn to thrillers that blend personal awakening with chilling conspiracies, and love authors like Robin Cook and Tess Gerritsen, you won’t be able to put this book down.

Kenzie has never had to work hard or question the people around her—until her sister dies unexpectedly in a hospital under circumstances that just don’t add up.

What is Unlawful Harvest About?

The more Kenzie digs, the more she finds that her sister’s death may be part of something far bigger and far more sinister. Unsettling discoveries pull her deeper into a medical mystery that challenges everything she thought she knew.

For the first time in her life, Kenzie has to stand on her own. And if she can’t get to the truth soon, someone else might die next.

Author Notes

Author Notes may contain spoilers!

I had a number of criteria for Unlawful Harvest before even starting. I needed a previously unpublished medical thriller for a multi-author collaboration. But I didn’t want it to be a stand-alone, nor a book that was later in a series (such as writing book #5 in the Medical Kidnap Files.) I wanted readers who were introduced to my writing through the collaboration to be able to have a logical “next read” in the same world or series. So before even starting, I had a puzzle to solve.

I decided to use Kenzie Kirsch, an assistant in the Medical Examiner’s Office in the Zachary Goldman Mysteries. The book could be Kenzie’s backstory, a prequel to She Wore Mourning, and the beginning of a new series. I wouldn’t have to change my schedule to write and publish more books in the Kenzie Kirsch series by the time the collaboration went live, because there were already four books published in the same world and more in the pipeline. 

I started collecting clues that had been dropped in the Zachary Goldman Mysteries about Kenzie’s past. Her apparent estrangement from her family, her red sports car, her attraction to Zachary Goldman but reluctance to jump straight into a serious relationship. Her amusement over Bridget’s behavior. Why didn’t she ever talk about her parents? Where does a medical student get the money to buy a fancy car? What had drawn her to the medical investigation field? And how could it all relate to a medical mystery/crime? 

Once I started to map these clues and requirements out, I hit on the idea of a very expensive gray-market organ transplant. I needed to do a good bit of research to bring myself up to speed on organ transplants, transplant tourism, finances, and the dark side of the transplant industry. You can find a few references about the organ trade in the Book Club Resources, but this is just the tip of the iceberg.
