Fun read and fun series. I keep deciding to finish the next book in the series and then move on to something else on my Kindle, but as I'm writing this I'm also downloading book 4.... This archaeological mystery series is great, Fan Kotler is a likeable, successful, and most importantly, flawed individual who you find yourself rooting for the whole time.

The Devil's Interval - a review by Rosemary Kenny*slight spoiler alertAnother world-class thriller that sees MC Dan Kotler and sidekick FBI Agent Roland Denzel fighting enemies, old and new on every side - even among Denzel's fellow law-enforcers - in a race to save the world's inhabitants from mass destruction by the eponymous mediaeval discovery, recreated by Isaac Newton, in The Devil's Interval, the third adventure in this series by the amazing Kevin Tumlinson.The murder of popstar Ashton Mi...

Entertaining Read, But....I am hooked on this series but it seems the author is stretching out the story with implausible plot twists and unanswered questions that are obviously there to set up interest in the next book in the series. It was okay after the Coelho Medallion, but the hanging plot thread of Gail McCarthy after Atlantis Riddle and in this book left me I satisfied with the ending and annoyed at the delicious berate hook to buy the next book in the series.

This is a nail-biting thriller as an attempt to create a means for the deaf to hear without cochlear implants goes violently astray and produces an unimaginable weapon for evil. The writing style is direct with a minimum of ancillary description. The characters are not particularly complex, but one turns out to be a real surprise. After an initiating murder, there is little violence until the end. However, the story is still suspenseful as Kotler uses his role as an FBI consultant to plumb deep

This is my third novel by Mr. Tumlinson. His writing continues to entertain and enlighten. In this story, we learn of hearing implants, high tech security measures, mind control from a distance. All combined,they make for an interesting read. I look forward to reading the next novel - The Girl in the Mayan Tomb.

Kotler and Denzel are back! The Devil's Interval is their next adventure, following the events that happened in The Atlantis Riddle. It's more of what I've come to love from this series with two fun main characters in Kotler and Denzel doing what each of them does best (and a little of what doesn't come best). If you've read either of the first two books, you already know what you're getting with this one, and that's a good thing! This story picks up a little time after the ending of The Atlanti...

Another 5 star read from Kevin Tumlinson. The Devil's Interval is book # 3 in the Dan Kotler series. As is the norm in this series, it is full of twists & turns. Dan's nemisis, Gayle, returns in an unexpected way. Was Isaac Newton on the verge of a mind control invention? Could modern folks who discover is workshop & notebook find his secret & expand on it? Dan, along with his FBI "partner"/boss, are on the hunt to stop what would be a disaster in the wrong hands. Read it; you'll like it.

Hearing LossThe story is about a breakthrough in audio technology for those with hearing loss. We have had cochlear implants. Now we have direct to the brain hearing, only something goes wrong and what we have is a new weapon that some will pay big money so they can control the minds of the world. Denzel and Kotler are thrust into the role of saving the world.

Unputdownable From the First Chapter As is the case with all Kevin Tumlinson's adventures I've read to date, this book was a thrilling page-turner. Dan Kotler is both brilliant and likable, the kind of hero the world needs. His talents and personality are well-counterbalanced by his partner, FBI agent Roland Denzel. There's just enough personal drama to allow this reader to connect with the characters without allowing the plot to become bogged down by it. Tumlinson writes with the skill and imag...

He is great! I love his works... he is an incredible author, and I love what he writes. He gets you hooked right in the first page or so, and there really is no letting go, as long as you have the time to do it, just read, I mean. I love this series, it is fun, interesting, educational, and a wild ride all rolled into one!!

The Devil's Interval(Dan Kotler #3)by Kevin Tumlinson This is a bit different from the other two books. It wasn't really an archeological dig or item. This was about mind control through a device made to help people. As corny as it sounds as I write this, it really was pretty good. Our hero gets kidnapped again! This book was unpredictable, not like the last book. Action packed, suspenseful, and quite the thriller!

Using long ago discovered technology, a charitable company has discovered a cure for hearing loss, but it has deadly consequences. Join Dr Kotler and Agent Denzel as they discover what lies beneath this amazing tech and try to stop it from taking over the world.

You have to read this book! I have now read all of the books in this series and every one of them are top notch, must read books!The research and talent that went into this book is compared to Dan Brown, maybe even better!I don't want to spoil this book for anyone, so I will stay vague in this review, but I have always wondered if the technology presented in this book was scientifically possible. I actually think it is to some degree possible, maybe not exactly in the same method presented in th...

A mind blowing thriller.Dan Kotler has been described as a mix of Indiana Jones and Robert Langdon, and that about sums him up. In this latest thrilling blockbuster he combats a mind controlling device inspired by the work of Isaac Newton. Five star entertainment from start to finish.

A Rolling Read And Great ThrillerKevin Tumlinson delivered again. The Devil's Interval is a great book and lefs through bad guys, tunnels, and more. Old and New. I like the character interaction. Now just me I would like a lttle more meat on the bones...details. However the author tries afterwards why the deails are sometimes thin. I may not agree...it just takes a little research...but this way books can be turned quicker and he explains that is what he loves to do. Me I like depth. But I still...
