Vengeance has returned to battle their old foe!


When a stable wormhole opens in Sol-controlled space, Vengeance and her crew wake from stasis to deal with the new threat.

Admiral Stansfield needs a team to investigate. The SBS has plenty of skilled operatives, but only Marine X is old enough to use the antiquated equipment they’ll need to complete the mission.

Redeployed from half a galaxy away, Ten just wants to get back to fighting the Deathless. He has unfinished business.

Stansfield is no fan of penal Marines, and Ten is pretty sure he’s hiding the truth about their mission. His teammates Conway, Kearney, Mason and Davies are still smarting over the loss of a comrade and aren’t welcoming either.

Can this ragtag squad unite to complete the mission at hand and save Earth from a conflict that could make the Deathless War look like a minor skirmish?


Buy Incursion, Book 1 of By Strength and Guile and find out how Ten and the SBS deal with the unknown dangers beyond the wormhole!

About the author

Hi, I'm Paul Teague, the author of The Secret Bunker Trilogy, The Grid Trilogy and the standalone novel, Deleted.

I'm a former broadcaster and journalist with the BBC, but I have also worked as a primary school teacher, a disc jockey, a shopkeeper, a waiter and a sales rep.

If you love stories like The Hunger Games, The Maze Runner, Divergent, Running Man and The Giver then you’ll enjoy my sci-fi and dystopian stories.

The Secret Bunker Trilogy was inspired by a family visit to a remarkable, real-life secret bunker at Troywood, Fife, known as ‘Scotland’s Secret Bunker’.

It paints a picture of a planet in crisis and is a fast-paced story with lots of twists and turns, all told through the voice of Dan Tracy who stumbles into an amazing and haradous adventure.

The Grid Trilogy takes place in a future world where everything has gone to ruin.

Joe Parsons must fight for survival in the gamified Grid, from which no person has ever escpaed with their life.

The standalone novel Deleted bridges the worlds of The Secret Bunker and The Grid, revealing what happens between Regeneration and Fall of Justice.

It depicts the world as we know it falling under a dark and sinister force - things will never be the same again.

I love dystopian fiction so writing these books has been a great opportunity to finally come up with my own vision of a future world where things are going haywire.

The Secret Bunker website can be found at: https://thesecretbunker.net/

The Grid website can be found at: https://thegridtrilogy.com/

I also write fast-moving and action packed psychological thrillers under the uathor name Paul J. Teague.

Incursion is a readable, action-heavy military science fiction story. Alien cyborgs try to capture starships full of armored marines. The book presents scene after scene of starfighter dogfights and hand-to-hand combat. The cyborg villains are over-the-top baddies who scratch “Death to Sol” on the hulls of ships they are boarding. I was therefore not surprised to learn in an afterword that Paul Teague’s favorite episode of Dr. Who is “Day of the Daleks.”
The By Strength and Guile trilogy is part of a shared universe originated by Jon Evans and his brother James. In sum, Incursion is about what you expect from independent space opera.

A terrific read

If you like fast-paced SF action, then this is the book for you. Space ships, mechs, and snarky royal marines, this book has it all.

I started reading this book without realising that there was a connection to a book I had just finished reading and discounted Commando by Jon Evans. Unfortunately it didn’t help that the prologue didn’t make a lot of sense and I really couldn’t face this book.
