The Coming Fire (The Coming Darkness Book Three) by Greg Mosse.

Published 17th July 2025 by Moonflower Books.

From the cover of the book:

First came the darkness.
Then the storm.
Now it’s time to face the fire.

Following a fighter jet crash in the Haitian hinterland, special agent Alex Lamarque is taken captive by a violent gang, the lone authority in this lawless territory.

His only allies are busy on the other side of the world, facing a crescendo of dangers: the AI viruses crippling the digital state; the breakdown of law and order; and some unexpected, terrifying news from a Paris observatory.

With no hope of rescue, Alex must take on his greatest challenge entirely alone. Survival will take every bit of strength he has.

***********

In the midst of global chaos, Alex Lemarque has crash landed in the Haitian jungle. The experimental jet is in pieces, his captive Davide Castile has escaped, and he has been taken hostage by a violent gang. With a mysterious AI virus wreaking havoc to all digital systems, Alex's divided allies are finding it difficult to reach him. He must find a way to free himself. Meanwhile, a new threat looms in the skies above the earth...

And so we have reached the final volume of Greg Mosse's ambitious cli-fi trilogy! The Coming Fire kicks off hot on the heels of The Coming Storm, which exploded in an orgy of cataclysmic events as the result of far-reaching conspiracies, and left readers very much in cliff-hanger territory.

This final instalment begins very much as it means to go on, flipping back and forth between multiple characters and locations to follow the scattered threads of the series to their conclusions - and Mosse has an epic task on his hands, because the previous volume took his protagonists far and wide in their slow-burn quest to save the world once again. 

Elements of tropical hell, Middle Eastern meltdown, danger on the high seas, dam-busted devastation, solar system shenanigans, AI induced cascading digital failures, civil disorder, and the monumental machinations of a madman all come crashing together in a mind-bending mash-up. There is a lot to keep track of (too much at times), and the changing pace between burst of action and Mosse's brand of slow-burn suspense is a little disorienting - especially when some of the threads venture back in time to explain pieces of the puzzle that happened off-stage.

There are nice surprises here though, that the fear of spoilers prevents me from revealing, so it is worth persevering to the pay-off, and never let it be said that Mosse does not know how to throw in highly original bumps in the road for his hard-working protagonists. His baddies are entertainingly pitched somewhere between Bond-esque meglomaniacs and Wilbur Smith-type wackos too, which makes them lots of fun.

Although I do not think either this concluding volume, or the mid-trilogy book (The Coming Fire), manage to hit the delicious page-turning noir delights of Mosse's debut, The Coming Darkness, there are some really thought-provoking concepts embedded here that show real promise when is comes to the intelligent way he tackles near-future Dystopia. I find myself left with the impression that less would probably have been more, but if you are game for a cli-fi series that goes all in then you will find lots here to please.

The Coming Fire is available to buy now in paperback, and ebook formats.
