The Planck Factor

Thoroughly intriguing! A real page-turner." — Zoë Sharp, author of the best-selling Charlie Fox series

On a dare, grad student Jessica Evans writes a thriller, creating a nightmare scenario based upon the theory that the speed of light is not a constant—one that has a dark application. Her protagonist (the fiancé of a scientist killed in a car crash) is pursued by those who

This book was warp speed and brilliant!

The speed of light =299 792 458 m / s or is it?

What happens if the speed of light is not a constant but an average? The implications can be disastrous. And the premise of Jessica's new novel, which she is unaware is her new found danger. But the truth is stranger than the fiction.

Jessica Evans, a Grad student, is writing a suspense novel as a challenge to create fiction worthy of

During Magic 101, my one (required) semester of college physics, the professor assured our class of history and lit majors that there was no such thing as calculus in the real world.

For the most part, that works for me. But every now and then something reminds me that I’m only seeing part of the universe.

Most recently, it was reading The Planck Factor by Debbi Mack, which asks a basic question: what if Einstein got that whole e=mc2 thing wrong? What if the velocity of light was NOT a constant, a

It was a good piece of sci-fi thriller. A bit confusing at one stage because it is a story within a story within a story. Once you get your head wrapped around that its very gripping.

For readers with a good attention span who enjoy Hitchcockian suspense set within the world of science and books about writers I write this review as a member of Rosie’s Book Review Team and thank Rosie Amber and the author for providing me with an ARC copy of this book that I freely decided to review.
This thriller (technothriller according to Amazon) tells a complex story, or rather, tells several not so complex stories in a format that can make readers’ minds spin. A thriller about a student w

I cannot count how many SF books I've read. I love reading about science. I love thrillers. I hoped to find something of all three in this book.
But sadley, no.
It was confusing. Not anough Planck and too much running around without achieving anything.

Review for “The Planck Factor” by Debbi Mack

Fascinating way of attempt by the author Debbi Mack presenting suspense thriller story with a hint of scientific development perspective and detecting a furtiveness in description. Entertaining readers with sequence of actions, dreadful secrets and mysteries gives book an impressive amount of thrill to feel. It’s a good pick for readers with great adventurous mind reflective to all action scenes and incidents for their passion for books.

When I got The Planck Factor, I thought I was getting a thriller with a solid science base. What I feel like I got instead was the insufficiently scripted screen play version of a good book. A mass market ‘science’ thriller for people who think that science is a word the CDC shouldn’t be saying.*

The Planck Factor had a few issues that really could have been rectified with stronger editing. The needless repetition, for one, got on my nerves rather swiftly. “Millions, even billions” was said a stu

This is a short book, a long novella. It's an unusual plot ~ student Jessica starts to write a thriller, then discovers that life is imitating art as she is swept into a cat and mouse chase involving mysterious men in vans, research into the possibility of making a bomb more powerful than a nuclear attack, truth seeker groups and murder.

I like Ms Mack's writing style very much; it's sharp, current and witty, and she has clearly drawn on her own experience to write Jessica, which was entertaining
The Planck Factor is a science fiction thriller about a young woman who gets tangled up in a world where everything we think we know about physics gets turned on its head. Being a physics major, I was drawn to this book primarily for this reason. Unfortunately, there just wasn't enough of this aspect of the story for me. The story is told in alternating points of view and is structured as a story within a story. It features a female lead, Jessica, a grad student who becomes the target of multipl ...more

"Hitchcock" at her best!!! Wow! A diverse plot told in a real time storyline with twists & turns.

This is not Debbie Mack's usual format nor content displayed in prior books! Mystery, science, atomic strength bombs, cloak & dagger, fiction turned reality while the writing is taking place... Geologists, geeks, gook squads, along with all the government alphabet agencies and even love affairs. Oh, I forgot to mention, a university student writing her thesis via a "dime-novel" format. Then s

I received this novella on NetGalley in exchange for an honest review.

I usually do not care for novellas, but Debbi's Mack's The Planck Factor will be the first exception. The premise and story line are so unique that the reader instantly becomes enthralled. In the prologue we are given the intrigue that drives the novel: a novelist, a spy, a secret anti-government group and impeding death. Sounds like a plot right out of an Ian Fleming novel, but Mack adds even more twists to add levels to thi

I received this book from an author's promotion.
A story within a story that does get a little confusing at times but if you pay attention to the chapter titles you won't have any problems.
Samantha is a student and is writing her first book. When her life starts to imitate things in her book she gets nervous. When she finds her friend murdered and becomes a suspect or person of interest - she gets on the first plane she can to her sisters. Strange phone calls, people following her, her sister me

This is a really fun thriller. The main character is a writer, who is writing a thriller. The book starts off with a lot of observations on the craft of writing, and really plays with multiple layers of the story in a number of ways, some absolutely obvious, some subtle.

There are two different world threatening scenarios as well, one of which is far more plausible than the other, but they're both fun (in a terrifying way). It's a great read, and I'm getting on Mack's mailing list because of it.

Interesting twist on mystery fiction

I enjoyed reading this book although I found some of the plot to be highly unlikely. I wished that there was more of a difference between the 2 main women characters.

Maybe Einstein was wrong…?

A fast-moving thriller/mystery with a smattering of science, a hint of global terrorism, and a novel-within-a-novel flourish that entertains.
