Her groundbreaking research is now under threat, and her life is in danger, as dark forces, both corporate and governmental, will stop at nothing to unlock the secret she carries.

With only days remaining before an event that could change everything, Denise turns to her ex, Navy Captain Ryan McNair. Together, they embark on a race to uncover the truth behind a mystery buried for centuries.

This was a DISASTER OF A BOOK. The storyline and characters were incredibly underdeveloped. I did not give a damn about anything happening to anyone in this book. The timeline of Denise’s pregnancy was unclear given that months were passing despite each chapter being named a day of the week. There were a lot of unanswered questions at the end of the book, and the answers and explanations we did get at the end were incredibly cheap and convenient. On top of it all, the writing style of this was atrocious. I would not recommend this to anyone looking for an enjoyable experience.

Thank you to Netgally for the digital arc. I have found that this is yet another example of cool cover not equaling a good book.

Maybe this book could be used as film script, and then it would make more sense… we don’t get much information about what is going on and the chapters were too long for me and named very strangely for what is going on, let me explain further;

Our main character, Denise for all we know is the main character, and she learns that she is pregnant, but to make things weird, she didn’t have intercourse, so no reason to be pregnant, and each chapter is named after a day of the week, but her pregnancy doesn’t have, nothing to do with the days, because in the first day she discovers she is pregnant, but in the third she is about 6 months… so I got really lost there…

While the story advances we learn that she is a scientist, working in genetic, is this pregnancy a test? Is it real? What is going on? I wish the story was a bit more science fiction, but its more thriller, also it didn’t help me to have different points of view (more like many things were happening at the same time from different points of view) in each chapter…

to be honest, I felt bored, and I couldn’t wait to finish… so the book dragged for months… Before reading, I thought it would be a kind of a feminist view of the world about pregnancy, so I got disappointed with what I got… I am sorry, possibly I wasn't the intended reader for this book.

Thank you Netgalley and HB Welbourne, for the free ARC and this is my honest opinion.

This is the story of Dr. Denise West, a renowned scientist who cured Alzheimer's. The story begins with Dr. West feeling the weight of stress and exhaustion from her work. She is pregnant, which is a surprise and a challenge to her carefully planned life. Weird things are happening: she sees a man in a blue suit and she finds her computer has been tampered with. Dr. West worries she may be the next target. No one believes her concerns and but the man in the blue suit reappears and warns her to pay attention to the signs, telling her they will guide her.

There are several characters and we along with Denise go through her trying to figure out who to believe and going through the twists and turns that make up the rest of the book.

The Hollis Code is a thrilling and suspenseful read that keeps you on the edge of your seat. The plot is complex and well-paced, with multiple storylines that converge in a satisfying conclusion.

The Hollis Code is a thrilling read for mystery fans of all backgrounds. It’s a fresh concept (I know I get sick of the same ideas recycled) from a new author (yay!), that should be sure to keep you on your toes throughout the narrative. The book contains spiritual, scientific, military, and governmental elements. These conflicting concepts create a tumultuous ride, topped with sprinkles of comedic relief throughout. The dark narrative presents a puzzle you might not be able to piece together until the end. Enjoy!

I love the concept and the storyline kept me guessing! I’m still not sure what the prophecy’s implications were and I can’t wait to see what happens in the next book!

What a fun riff on the miraculous conception… sort of did she or didn’t she. The aperture ending may not be satisfying for everyone but I loved it because it made me think
