When a leading professor at a top-tier medical research institute accuses a colleague of drugging and sexually assaulting a student, department chair Brad Parker and university detective Karen Richmond join forces to investigate, only to be stymied by a victim who can't remember what happened. But as fragments of memory resurface, she's brutally attacked and murdered. The conclusion is obvious, but in the absence of forensic evidence, police hit a wall—until Brad and Karen's inquiries take an unexpected turn that not only threatens their own lives, but exposes a cover-up at the highest levels of the university.

Nondisclosure: A Medical Thriller takes a frightening look at a culture that promotes sexual misconduct in academic life.

This is a thriller that took place at big college. Their was a student raped, and this book is trying to find out who did it. It is a short book, but it gets a lot done in it. I enjoyed it a lot. This book was well written, and I really enjoyed the characters. I found the mystery parts of this book to be really good. I won a copy of this book from a goodreads giveaway, but this opinion is 100% my own opinion.

Academia, the hallowed halls of education, research and the true test of the human brain to excel. Among the cerebral hide the monsters, the power mongers, those charged with molding and stretching young minds who would also become sexual predators and possibly cowardly killers. Enter Geoffrey M. Cooper’s world where the rules of NONDISCLOSURE give free reign for the monsters to move on and devour new prey.

When a colleague is accused of sexually assaulting a student, department chair Brad Parker will become part of the investigative team to prove or disprove the charges. Out of his comfort zone, he soon finds the thread that will lead him through a maze of deceit and cover-ups as the great machine barrels forward hiding the skeletons in the closet that could end the financial boons for research.

Geoffrey M. Cooper adds enough grit and enough mystery to hold readers enthralled while exposing sexual harassment for what it is, a hideous act of a twisted mind.

Wonderful scenes and settings, characters out of their comfort zone, yet willing to do whatever it takes for justice.

Page after page of bold storytelling that will unravel the truth at the end without using over-theatrics, just gifted writing.

I received a complimentary ARC edition from Geoffrey M. Cooper!

This is a terrific, fast-paced thriller. When a student at Boston Technological Institute is assaulted, Dr. Brad Parker and investigator Karen Richmond are assigned to work together to find the perpetrator, but what they uncover is a confusing, sometimes seemingly contradictory set of facts. When the crimes escalate further, they find themselves struggling to unravel a web of corruption concealed by the political machinations of academia.

The plot is well-constructed and fast-moving--fans of Cooper's excellent first novel "The Prize" will instantly recognize and enjoy the same engrossing writing style. The two lead characters are both very likable, and the story takes them on plenty of twists and turns along the way.

But what really stands out about the book is that it shines a light on how corruption can happen even in institutions that we normally think of as forthright, honorable, and respectable. As the old adage says, "power corrupts," and this is no less true of power wielded by people in science and education than anyone else.

I highly recommend this book to fans of thrillers--not just medical ones, although there is plenty of interesting medical science interwoven with the plot. But even someone like me, with next to no knowledge of medicine, chemistry etc. will appreciate this gripping tale.

In “Nondisclosure,” Cooper gives us another fascinating glimpse into the not-so-pretty sides of academia. While his first novel, “The Prize,” takes us into the competitive world of medical research, “Nondisclosure” delivers us into the #MeToo world of sexual harassment and assault. The story is as much a mystery as it is a medical thriller, giving the reader the opportunity to try to figure out whodunit, which I thoroughly enjoyed. Plus, Cooper handles the subject matter sensitively, all while creating a hero to root for and a reason to do so. Fluid prose and scene-setting description further enhance the page-turning pace, making the book a smooth and highly enjoyable read.

This may be the worst book I've ever finished. It was so amateurish that I thought it was self-published. The author is obviously a science professor. He knew the science (I assume) and the workings of university science departments. However, the writing was good for a high schooler and the dialogue excellent for a middle schooler. I thought the plot was a good one, so I kept on (skipping paragraphs where the obvious was related). I think in the hands of a good author, the plot outline could have resulted in a good book, but even then, there were silly opportunistic incidents that saved the hero and heroine.

So many books. This is one to skip. Sorry, Prof.

I enjoyed the author's portrayal of present-day academia and the way scientific research is done at universities. Since this is a crime thriller, the focus eventually shifts to dirty deeds. Sadly, I suspect reality is not too far from the fictional situation presented here.

The characters were engaging but not particularly memorable. I was a bit annoyed at the sexual relationship that develops rather briskly between the two main characters, especially given that their initial contact is purely professional and involves accusations of sexual assault.

That said, this was an entertaining and interesting read. The prose is clear and direct, with just enough description of characters and settings.

Highlights the frustrations of people that abuse their power. Anticipated a twist and story definitely picked up them. Was satisfying for certain characters to get some of what they deserve

Ok it wasn’t that it was bad I’m just annoyed how they looked right past the OBVIOUS bad guy from the jump. She was giving rookie detective throughout this book. The setup was good, plot was solid and flowed but the characters are unlikeable. I still have the next book in my physical TBR so we will see if I pick it up…

This was such a page turner! It had me hooked from the first paragraph and I read it in two days, barely putting it down. I don't think I've ever read a "medical thriller" before, but don't let that title indimidate you. It had all the great whodunit and mystery elements mixed in with lots of science and details that I found fascinating. The whole sexual assault accusation stuff fits right in to all the madness that's happening in the national spotlight and the book kind of gives it two different perspectives that are interesting to say the least. Both main protagonists are believable and likeable and there's the usual sexual tension and romance that always gives a book like this a playful edge. I really loved Nondisclosure and look forward to reading more from Cooper.

Geoffrey M. Cooper's Nondisclosure: A Medical Thriller is technically a medical thriller because most of the characters are involved in medical research. But, it's really a case of which suspect raped a female researcher after a dinner to celebrate a research breakthrough. Not much plot, but a few surprises.

This was a great, fast-paced, short book. It jumped into the set-up of the story very quickly and was easy to read. It really held my attention throughout the entire book and drew me into the story. The writing was good and easy to follow and read. When one of Brad's students is killed, he teams up with Karen Richmond to try to find out what happened. The investigation takes them into unexpected places, and who could possibly be involved in the scheme? There are a few twist in the book and it is not solely the investigation, but also the lives of the characters. I have already started the second book in the series, as this was very good. You also do not need a science background to follow and understand this book. I recommend reading this book.

What an amazing read this was. This book grabbed me and drew me into the story immediately. Brad, as a University professor, is relentless after rape and murder of a student in his belief that the wrong person has been found guilty of the crime. Brad and Karen, an investigator with the University Police Department, are successful in solving the mystery and bringing justice to multiple unknown victims from the past. The book is very well thought out and written and I would certainly recommend it to anyone that loves a good thriller. I did win this book through Goodreads.

What a disappointment of a book. This entire book could have been summed up and finished in less than 10 pages. The rest was filled with unrealistic characters, laughable "romance", & the "bad guy" was obvious from the get-go. If it hadn't been such a short book I would have left it unfinished. There was no character development at all. I found myself irritated with all of the undeveloped situations and people in this book. It felt like it was written by a high school, if not grade school, author who was in a hurry to get something on paper.

Interesting plot and characters. Perfect pacing for a pool or beach read. Surprises and good character and plot development. A little bit disappointed that there wasn't more about the research that was only discussed briefly, yet a key element in understanding motive. Enjoyed discovering that academic settings can be as good a source of the power-driven conflicts we have come to accept in corporate settings.

This is NOT a medical thriller as the title clearly states. There is no hospital, MD, DO, nurse, doctor's office, clinic or any of those elements you expect to find in a "medical thriller". The setting is a university, and the characters are professors and students. It's more of a college whodunit. It kept my interest well enough, but I would not recommend it my friends.

Liked this a lot

Academia is a place for learning and research. As we find in this story, it's also a place to find greed and evil . Nicely written , good intro to scientific research and university politics .

Interesting plot set in the cutthroat world of academic research. Action moved a bit slow for me and the relationship between Karen and Brad took unrealistic steps. Wasn’t what I expected in a medical thriller.

Excellent writing and a twisty plot from an author who clearly understands academia. Sadly, the most unrealistic part of this book is that a victim would get any justice at all.

Good but predictable

It was a light weight, quick read. Knew who the bad guy was in the beginning, just not how. First book I read by this author.

This wasn't really a medical thriller in my opinion. The action is in the university and research world, don't expect to read about doctors or hospitals. But it's a solid 3,5.

Well worth the read

Well written, with believable characters and dialogue, a plot with more twists than a constipated snake, and a highly implausible start to a romance
