Sergeant Adriene Valero wants to die.


She can't.


After enduring a traumatic resurrection for the ninety-sixth time, Valero is reassigned to a special forces unit and outfitted with a cutting-edge virtual intelligence aid. They could turn the tide in the war against intelligent machines dedicated to the assimilation, or destruction, of humanity.

When her VI suddenly achieves sentience, Valero is drawn into the machinations of an enigmatic major who’s hell-bent on ending the war—by any means necessary.

The Last Watch


The Divide #1



The Expanse meets the Night's Watch from Game of Thrones in J.S. Dewes's fast-paced, sci-fi adventure where a handful of soldiers stand between humanity and annihilation.

The Divide.

It’s the edge of the universe.

Now it’s collapsing―and taking everyone and everything with it.

The only ones who can stop it are the Sentinels―the recruits, exiles, and court-martialed dregs of the military.

At the Divide, Adequin Rake commands the Argus. She has no resources, no comms ― nothing, except for the soldiers that no one wanted. Her ace in the hole could be Cavalon Mercer — genius, asshole, and exiled prince who nuked his grandfather's genetic facility for "reasons."

She knows they're humanity's last chance.




“Dewes’s debut is an exciting, fast-paced ride around the edges of the universe, where those rejected by much of humanity are the only ones who can save it. Fans of K. B. Wagers’s ‘Farian Wars’ series and John Scalzi’s Old Man’s War will welcome this military science fiction thriller.”

Library Journal, starred review

“The Last Watch is
a bravura debut that blends great action with compelling characters, lighting up this new series.”



"An epic tale of survival at the end of the universe.”

— Megan E. O'Keefe, author of Velocity Weapon

“The Last Watch is an amazing debut. The smart world-building and explode-off-the page action scenes make it perfect for fans of The Expanse and other fast-paced Sci Fi. I predict that Dewes is going to be a 'must read' author for years to come.”

— Michael Mammay, author of Planetside

“The Last Watch by J.S. Dewes is as spectacular a science fiction story as one is going to find. From a plot that is full of drama to amazing characters that are relatable and interesting, all over a backdrop of a futuristic space setting, The Last Watch is nearly flawless."

FanFi Addict


The Last Watch has it all! Risky orbital maneuvers! Knife fights with grotesque aliens! Mysterious ancient artifacts! Secret royalty! Tragic backstories! It's classic military space opera with a touch of the cosmic.”

— David Levine, winner of the Andre Norton Award for Arabella of Mars

“J.S. Dewes' impressive debut...features big ideas, kick-ass characters, and an environmental collapse; you have to try to not be interested in this book. Highly recommended!”


"Gripping space opera debut. Sharply pointed descriptions . . . Dewes fluidly interweaves complex worldbuilding with a fast-moving plot and satisfying character development . . . This should win many fans."

Publishers Weekly

"Both readers are brilliant and nail the characterization in a way that instantly connects them to the listener. Everything here is top-notch. Dewes has created a gripping, fast-moving story that is excellently told by the readers.”

- Booklist, audiobook starred review

“Crisp writing, vivid characters, and a plot that beguiles the imagination. The Last Watch is a stunning military sci-fi debut. I was hooked from the opening lines. If you like science fiction, then this book is definitely for you.”

— Jasper T. Scott, USA Today Bestselling Author

More fun than that time The Expendables, the Dirty Dozen and all of The Night’s Watch all got picked up by a random quantum tear in the fabric of spacetime and shot out the edge of the universe to kick ass and save humanity.”

— John Birmingham, author of the Axis of Time trilogy


“Take the action of Marko Kloos' Frontlines novels, mix in the intricate world building of Game of Thrones or Warhammer 40,000, and light the fuse. . . . Bursting with snappy dialogue and detail and furious with action, you’ll want to catch your breath when it’s over, and then you’ll want more. Bring it on.”

— Dayton Ward, bestselling author


A scary edge-of-reality setup, cool martial-arts tattoos, interesting time anomalies, and OMG! The Universe is contracting!? Clear your schedule, because once you've gotten on this roller coaster, you're not going to want to get off until you've ridden it to the end.”

— Emily Devenport, author of Medusa Uploaded

The Exiled Fleet


The Divide #2


J. S. Dewes continues her fast paced, science fiction action adventure with The Exiled Fleet, where The Expanse meets The Black Company—the survivors of The Last Watch refuse to die.

The Sentinels narrowly escaped the collapsing edge of the Divide.

They have mustered a few other surviving Sentinels, but with no engines they have no way to leave the edge of the universe before they starve.

Adequin Rake has gathered a team to find the materials they'll need to get everyone out.

To do that they're going to need new allies and evade a ruthless enemy. Some of them will not survive.

“The surviving Sentinels of 2021’s The Last Watch face starvation and madness at the edge of the universe in the thrilling second space opera of Dewes’s Divide series . . . Well-crafted intrigue, tense battles, and a lot of heart make for a page-turning adventure on the way to a conclusion that will leave fans anxiously awaiting the next installment."

― Publishers Weekly, starred review

“Dewes knows how to twist her story in unexpected directions and pull her well-drawn characters out of impossible situations.”

— Booklist, audiobook review

"An absolutely superb follow-up...a sequel that manages to be different while still capturing the kinetic energy of the first book. Dewes has proven once again to be a master of pacing & tension & knifing you in the heart. I am so glad I took a chance on this space adventure series, because it’s on track to be one of my favorites of all time."

– Realms of My Mind

"The book’s far future setting has characters who are racially diverse and emotionally relatable, with themes of military control, genetic engineering, and alien contact . . . Dewes’s follow up to The Last Watch keeps the action front and center, while presenting an expansive science fiction story that is both richly complex and accessible."

― Library Journal

"One of the best parts about The Last Watch was how a cobbled-together, rag-tag assemblage of characters and technology still eked out a victory. I’m happy to report that the same white-knuckle, skin-of-their-teeth excitement is here from the very first page. So, too, are many of the characters that made the first installment great, as well as some welcome new arrivals."

— BookPage

"An excellent follow up...It builds on everything I loved about the first book and delivers more insight into the Divide’s universe. This is a series to watch. Highly recommended."
