Editorial Reviews


Meghan Amazon Top 1,000 Reviewer - For some reason, JC Ryan's thriller, 'The Tenth Cycle' reads like the offspring of a Tom Clancy and a Clive Cussler partnership--although JC Ryan can easily stand on his own as an exciting literary force to reckon with. 'The Tenth Cycle' is deeply suspenseful, and right at the get-go, grabs you by the cuffs and compels you to keep turning the pages--and that doesn't even begin to describe what a deliriously entertaining book this is.

At its heart is a conspiracy: a secret about mankind that--if and when revealed--will radically change not only the way men live and think, but also about how they'd regard their future. The secret is zealously guarded by shadowy characters and organizations that put the lives of the two protagonists, Dan Rossler and Sarah Clarke, in grave peril. When academic ridicule intensifies into outright hostility and possibly fatal threats, that's when Dan and Sarah know they're onto something ground-breaking. But then there's the rub--the forces guarding the secret will stop at nothing to guard it and keep it from discovery.

C'est Moi Amazon Reviewer - Definite MUST READ!!! This book is fascinating, keeps you guessing and is truly a work of art! 10 STARS!!! This book is absolutely awesome!! It's complex, but not difficult to keep up with, the characters are three-dimensional, and the author makes you really care about them and feel as though you are part of their group. I truly did not want it to end. This is a book for everyone! 

The mysteries discussed here are more than likely things you've wondered about yourself. I know I have!! Mr. Ryan really brought this tale to life and, form, it was like watching a fascinating movie that was over far too soon. I could visualize every single part! I was so involved in the story that, when I was unable to read, I was thinking about the book. I'm thrilled to have found this author and even more thrilled to see he has many more for me to dive into as soon as possible. The Ninth Cycle is already loaded and ready!

Even though I read this book through my Kindle Unlimited subscription, I just purchased it so I could keep it in my digital library to read again, at will. I would give this book 10 stars if they'd let me. I can't say enough how much I truly enjoyed the journey I took with the Rosslerites!!Thanks so much for such a wonderfully written, and well researched story, Mr.Ryan. There's not one thing about it that I would change!

I'm really looking forward to the next book, as it discusses the very controversial Piri Reis map of 1513, and the possible coast of Antarctica without Its icecap!!

PBBJR Amazon Reviewer - An excellent read and wonderfully crafted work, I quickly became addicted to the series. Mr. Ryan has created an entertaining thriller with lovable well developed characters and a fascinating subject matter. This is truly an intelligent thriller.

S Coyle - I absolutely loved this book. The characters are believable. It is one of the best books I have read in years!!!

1.0 out of 5 stars Thrillers should be thrilling, this isn’t.
Reviewed in the United Kingdom on August 31, 2020
I loved the sound of this book, the synopsis definitely had me intrigued but, just 46 tedious pages in, I’m giving up.

The amount of gushy pining the two main characters have done for each other in such a short space of time is a bit vomit inducing and there seems to be little sign of any story developing beyond their rather boring attraction to each other.

If you like romance novels perhaps this may be for you, if you like thrillers then it’s probably not.
