An officer hangs himself in the engine room of naval submarine HMS Tenacity. A woman's murder bears disturbing similarities to an old case. Lieutenant Danielle "Dan" Lewis grasps for the truth before it submerges in the gray waters of the English Channel.
Cramped, claustrophobic, and under strict command, the confines of HMS Tenacity are unwelcoming in the best of circumstances. For Dan, the only female aboard, who must methodically interrogate a tightknit and hostile crew, it's her own special place in hell.
Recently reassigned to the Special Investigation Branch's Kill Team, Dan's hardheaded reputation precedes her. But facing an obstinate ship's company, a commanding officer too eager to close the case, and a constant threat of unfriendly male interest, she learns that under enough pressure everyone has their breaking point.
A nuclear hunter-killer submarine that runs out of Devonport in the UK. Like other Trafalgar-class submarines, the HMS Tenacity will soon be phased out to make way for new Astute-class submarines. Dan's investigation on board the Tenacity takes place during the boat's last trip out.

Commander Roger Blackett
Head of the navy’s Crimes Involving Loss of Life division (aka Kill Team). Roger is a loyal friend to Dan. He tries to help Dan with her investigation but, ever stubborn and self-reliant, Dan will only allow him to help so much.
Chief Petty Officer Stewart Walker
Following the murder of his wife, Cheryl, Stewart Walker is found hanged on the Tenacity. Dan’s job is to investigate Walker’s suicide, but she thinks there is more to his death than that.

Commander Melvin Bradshaw aka the Old Man
Captain of the Tenacity and the longest-serving submariner still on an operational submarine. The Old Man is prone to extreme mood swings and makes no secret about how disgusted he is to have Dan interrogating his ship’s company.
Lieutenant Commander Aaron Coles
An old acquaintance of Dan’s and a current member of the Tenacity. Aaron is respected by the ship’s company and is also one of the few friends Dan has on the submarine.
Steward Ben Roach

Coxswain on the Tenacity. Though not as close to Dan as Aaron Coles is, Jago is a welcome friendly face.
Lieutenant Richard McCrae
A member of the Tenacity’s company and an unabashed misogynist. Lieutenant McCrae seems determined to make Dan’s trip on the submarine as uncomfortable and difficult as possible.
“J.S. Law is a powerful new voice, and his heroine Dan Lewis lives up to the title. She is fearless and doesn't quit in the faces of all odds. The murky world of submarines and murder make Tenacity addictively readable, and memories of it linger like dreams.”
— Patricia Cornwell, #1 New York Times bestselling author
“Now and again, a debut novel comes along that makes you hold your breath. Tenacity by J.S. Law is one such book. Its authenticity rings true with not a false note throughout. Tense, claustrophobic, and totally absorbing, this book should be on every thriller reader's radar-or should that be sonar? Absolutely superb.”
— Matt Hilton, author of Blood and Ashes
“A taut, tense thriller with a fantastic female lead. The prose is crisp, the humor dark, and there's just the right amount of detail to ensure this has a massively broad appeal. Hard to believe this is a debut. J.S. Law is one to watch.”
— SJI Holliday, author of Black Wood
“Pacy, claustrophobic, and utterly thrilling, with a heroine you'll happily follow to the bottom of the ocean. Tenacity is a highly original debut by a major new talent.”
— Eva Dolan, author of Long Way Home
“Tenacity by J.S. Law is a brilliant debut. Breathlessly plotted. Deeply disturbing. The perfect thriller to dive into this summer.”
— Emlyn Rees, author of Wanted
“J.S. Law's taut crime novel oozes authenticity. I read this in a day and can't wait for the next in what will undoubtedly be an explosive series.”
— Clare Mackintosh, author of I Let You Go
“An impressive debut novel...Law knows what he's writing about, and it shows. The sexist antagonism of the men coupled with the cramped conditions make for gripping, entertaining reading.”
— The Times (London)
“It's a dark tale set where the sun doesn't shine. If Law manages to hold his course into nuclear noir, this series could go for as long as the atomic-powered Tenacity.”
— The Sun (London)
