Tenacity is a read that I thoroughly enjoyed. Its main character is Danielle Lewis (Dan for short) an investigator with the Royal Navy and I really liked this idea, it made a very welcome change from the usual scenarios in the genre.

A woman in a man’s world, who has already fallen foul of the establishment and seems to be hanging on to her career by a thread, she is investigating events around a suspected suicide on Tenacity, a nuclear submarine. This is a debut novel although you could be forgi

This is an excellent thriller, and way more polished than I would expect from a first time author. The protagonist is Danielle (Dan) Lewis, a member of the Special Investigation Branch of the Royal Navy. Dan has recently returned to work after a traumatic experience and professional screw up. She has been specifically requested to be assigned to investigate a possible suicide on the submarine Tenacity.

The author is a former member of the Royal Navy Submarine Service. That experience pays off wo

An excellent debut thriller in what appears to be the first of a series.

Danielle (Dan) Lewis is a member of the Navy's Special Investigation Branch and is asked to investigate the suicide of Stuart Walker, a crew member of the nuclear submarine HMS Tenacity. Stuart's wife Cheryl had been raped and murdered only a few days previously while Stuart was still on the submarine and Dan has an inkling there is more to the story than a simple suicide. Dan has been in trouble previously in her career fo

I started Tenacity last night and apart from a short sleep, a work shift and you know, feeding the kids, I didnt put it down until I finished it just now. Really, don't start this book until you have a chunk of time free.

Tenacity is a claustrophobic, addictive and brilliantly constructed thriller that just won't let go, utterly gripping and pretty perfect. Dan, a woman in a man's world, is superbly drawn, anchoring the tale, allowing a lot of fairly dark themes to be explored all wrapped up in a

WOW! A rather superb debut set below the sea, in a submarine.

‘Tenacity’ takes you into a world of claustrophobic nightmarish submarines and murder. One woman is seeking a killer. HMS Tenacity is a nuclear submarine stationed on the south coast, with an all male crew. Danielle Lewis or Dan as she is known, is in charge of an investigation into the suicide of one of the crew members. Dan is suspicious because the crew member’s wife was murdered, just days before. Dan finds herself on board the sub

This is an unusual thriller, featuring Navy Officer and Special Investigator, Lieutenant Danielle Lewis. The story begins with a flashback of events in 2010, when Dan Lewis confronted murderer Christopher Hamilton. This investigation is to haunt Dan, cause a rift with her partner, John Granger, who had no idea she was intending to go off on her own without backup, and damage her reputation.

We now move forward to 2014 and find Dan living alone, still struggling with the aftermath of the Hamilton

As you can see from the blurb, DI Danielle Lewis is female investigator in the Royal Navy’s Special Investigation Branch. She is called in to investigate an apparent suicide of a submariner on board submarine Tenacity. What we also find out is that the apparent suicide's wife has been murdered too. Are the two events linked? This is what drives our heroine 'Dan' on. Working in a very much male dominated world, Dan goes to great lengths to not play on her feminine side hence adopting the name Dan ...more

You have to read this book!

Yes, it’s another of those books I’m going to rave about. Another of those books that I already know has made it into my top list of books read this year (when I create it at the end of the year).

It had me hooked from the very start with the prologue – which can I just say, was stunning! – to the very end of the book, which has now left me wanting to know when J.S.Law is going to be bringing the next book out.
Let me explain a little more… Dan, short for Danielle, is
Such a high quality thriller with a fantastic and unusual location - tense and claustrophobic, it grips instantly. A great debut.

Seldom has a book irritated me as much as J.S. Law’s debut novel Tenacity. And that is saying a lot, because over a lifetime of reading, I have been exposed to some real stinkers. So what makes Tenacity stand out?

Well, how about this? The thriller is intended to introduce a character that will continue on in a whole series of books about her exploits as an investigator in Britain’s Special Investigation Branch’s “Kill” Team. In layman terms, that means that she is a homicide detective who works

Tenacity – Exciting Crime Thriller Debut

JS Law blasts in to the world of crime fiction with a spectacular debut and introducing us to a tough but vulnerable Special Investigations Investigator in Lieutenant Danielle Lewis. Tenacity takes us in to the tough macho world of a submariner where women are as welcome as a pork pie at a bar mitzvah. JS Law has used his experience as a naval engineer to give an insight in to some of the mindset of the Royal Navy and gives us a hero we can admire for her

Picked this book from the new shelf at the library yesterday, rushing to collect the book on Putin that I wanted to read before the holiday library closure. I see that this book is listed here as #1 in what will be an ongoing Lt. Danielle Lewis series. It is excellent for all the attributes expected from a tense thriller: pacing, setting, action, despicable baddies. On the attributes alone, Law's debut novel deserves 5 stars. But the protagonist! One third of the way into the book, I started men ...more
Tenacity was an unexpected thriller (in a good way) that was refreshing, suspenseful, and introduces readers to a heroine in a unique situation.

Lieutenant Danielle “Dan” Lewis is an investigator for the Special Investigative Branch (SIB) of the British military, and the lone female investigator at that. Following an investigation that both heralded her as a hero and reviled her amongst her colleagues, Dan has come back to her roots after taking a year sabbatical. What her colleagues are unaware

Lieutenant Danielle Lewis is just coming off a year's leave and is assigned a case on a submarine wherein a sailor she knew from training committed suicide. His suicide comes quickly after his wife was killed after being raped and beaten. Her death was very like another attack that is haunting Dan and was a large factor in the reason she took her leave.

Dan finds herself investigating on a submarine where she is the only woman on board and the only outsider. She is subjected to sexual harassment

Despite getting off to a slightly slow start, plus an incredibly engaging prologue, Tenacity soon ramps up the compulsiveness of reading, with its claustrophobic setting and no clue how on earth it would turn out.

It's the location of this book that is the stand out and what attracted me to the book in the beginning. It is not often you get a book set on a submarine, written by an ex-Navy person. It is even rarer to be able to read a chilling murder and having just a singular Lieutenant

The prologue to Tenacity provides a gripping opening that grabs our attention from the first. In his debut novel author JS Law launches an exciting new female character in Lieutenant Danielle Lewis. It revolves around the Royal Navy’s nuclear submarine HMS Tenacity. We quickly find ourselves submerged in the story as we enjoy this breathless paced thriller. A really excellent debut that is well written and a great read.

This book was a decent thriller. It introduces Lt. Danielle Lewis as a member of Britain's Special Investigation Branch, military police I guess. She is to investigate suicide that occurred on a submarine. The submariner's wife had also just been brutally murdered and she was also to look into the alibis of the crew (sorry - ship'd company) at the time of that murder.

To cut a long story short, she ends up going on exercises on the submarine to continue her investigation. She is the only woman on

enacity is a fast-paced thriller. It's the first one I have across that's set on a submarine and I was engrossed from the start. It's a fascinating story, with great descriptions of submarine life. I feel like I learnt a lot by the end of the book.

Set in a submarine and revolving around murder of Navy man and wife.

A quite thrilling book,which was quite a good read.This is the first in series,and I might go back again to read more about Dan.

I particularly enjoy books that are set in places I’ve visited or lived in so this book appealed as I’m familiar with many of the locations in this book being a Forces child and from a Naval family that lived not too far from Plymouth. I liked that this book is different being set away from the bright lights of the bigger cities and also its unusual setting.

Tenacity, by JS Law, is a searing thriller set within the confines and traditions of the Royal Navy. The pressure rises when the unstoppable force of a tenacious investigator meets the immovable object of naval comradeship on board a submarine. The claustrophobic drama which unfolds is breathtaking.

Can I come up for air now?! Tenacity is absolutely brutal in its intensity and is quite easily one of the best debut thrillers of 2015. I received my review copy a couple of months ago but somehow managed to hold off reading it until July, despite the fact I had loads of people telling me on Twitter that I should be reading it (Grab This Book shouting the loudest)! Sometimes though part of the excitement of a book is knowing that you've got it coming up on your TBR.

From its shocking opening scenes to the tense finale Tenacity was a gripping read. Scenes play out in the claustrophobic confines of a submarine and James Law captures the tension on every page.

Lieutenant Danielle (Dan) Lewis is one of the Navy’s best investigators, however, as Tenacity opens we find Dan has placed herself into extreme peril by acting on her own initiative and has not waited for back-up from her colleagues to pursue her lead. The fallout of her actions have repercussions, Dan lo

My husband served in the Royal Navy aboard a nuclear submarine, so I started with a vested interest in this book. I'd read very few pages before that incentive disappeared-- sucked into a fast-paced and fascinating narrative that I didn't want to put down.

The book's title also describes Dan Lewis. Once she gets an idea into her head not even dynamite is going to dislodge it. Her upbringing-- being a part of "Clan Lewis"-- has given her bad habits. Her family is an extremely competitive one that

It is hard to believe that this is a debut book it is so very well written. Living in a Naval city and coming from Naval stock I am quite familiar with this side of things in the book and I was a little nervous when I first started reading that it wouldn't reach my expectations. I shouldn't have been worried, this author definitely knows his stuff (and so he should given his own background) and it came across on the written page as very realistic. At times I was myself transported to the submari ...more

The Dark Beneath, previously marketed as Tenacity by J. S. Law has been on my radar (no pun intended) since it was first released, but I hadn’t gotten around to buying it until recently! Having heard that there was a second instalment coming featuring Dan Lewis (The Fear Within), it was high time I bought this. I’m a huge thriller fan, and I love all things nautical/naval, so I had a feeling this would be one I’d enjoy. Couple that with the RAVE reviews from bookish friends, I had a feeling I’d ...more

Lieutenant Danny Lewis is a member of the Special Investigation Branch's Kill Team in the British Navy. Having broken a famous case several years earlier, and almost been broken by enemies within the Royal Navy, she is assigned to the obvious suicide of a crew member of a nuclear attack submarine. The case is viewed by those above her as something to dispose of neatly, but she doesn't work that way.

Tenacity is a stunning debut which has a unique setting for the vast majority of the book that helped to make it the absorbing read that it is. The main character is complex, interesting and likeable. The quality of writing is remarkable, especially since the main character is a woman and the author is a man. The only other book that I have read with a female main character written in such a believable way by a male author was Before I Go To Sleep by S. J. Watson, and although these two books ar ...more

When you don't like being under water, not at your most comfortable in the dark and really don't like enclosed spaces Tenacity was always to be a read that was a little bit uncomfortable.
Dan has to investigate a suicide/murder and due to circumstances has to do so from the submarine called Tenacity. She isn't happy with her surroundings, problems she has had previously are affecting her judgement and she is receiving horrendous treatment from some of the naval crew.
She definitely has her fault

A thriller in a submarine: why hasn’t it been done before? Well, it has, in a way — in the (cold) war time story worlds and Tom Clancy et al — but not like this.

Danielle (‘Dan’) Lewis is the willful and likeable Royal Navy special investigator at the centre of a plot that rattles along, as she looks into a related murder and suicide.

Two things jumped out at me about this book.

One is the author’s rich knowledge of this world — not just the up-to-date details of nuclear reactors and emergency bre
