About this listen

 'METICULOUSLY PLOTTED, EDGE-OF-YOUR-SEAT SPACE OPERA WITH A SOUL' Kirkus on Velocity Weapon

In the final book of this explosive Philip K. Dick Award-nominated space opera, the universe is under threat and an ancient alien intelligence threatens to bring humanity down - unless Major Sanda Greeve and her crew can stop it . . .

The code has been cracked. The secrets of the Casimir gates have been revealed. But humanity still isn't safe. The alien intelligence known as Rainier and her clones are still out there, hell-bent on its destruction. And only Sanda can stop them.

With the universe's most powerful ship under her command and some of the most skilled hackers, fighters and spies on her team, it will still take everything she has to find the key to taking down an immortal enemy with seemingly limitless bodies, resources and power.

Critic reviews

Catalyst Gate and The Protectorate series is a must Sci-Fi read (FanFiAddict)
Catalyst Gate ends a trilogy that I gave high marks to across the board. I really loved this story. O'Keefe's writing moves at a blistering pace. There's a protagonist with disability, several LGBTQ+ relationships, and traumatic challenges to overcome. Wild ideas, cool tech, wonderful representation, and suspenseful as hell - an easy recommendation for anyone looking for a grand adventure in the stars (FANTASY BOOK REVIEW)
Catalyst Gate is the smashing finale to a trilogy that was already poised to be one of my favourites of all time . . . If you're a fan so far, you'll be well rewarded; if you haven't started the series yet, rest assured that it's a journey well worth taking" (REALMS OF MY MIND)

Most relevant
This series is enjoyable from the start. The writer mixes emotions and relationships with grand plots and galactic processes with ease.
I found the narration of the first book a little jarring at times but the performance improved with each book, perhaps as the characters became more familiar.

If you enjoy the likes of Peter F Hamilton or Alastair Reynolds then you will find a new universe and writer here to satisfy your sci-fi itch.
I can't wait to start her next story.

A great curtain draw for an exceptional space opera.

Good story, very well read. A little convoluted and a touch flabby in length but the performance carries it through. Probably 25% longer than it needs to be but again good performance. Story drifts a bit and doesn’t entirely make sense but a good yarn nonetheless

Good story if a little convoluted

Great stuff we wrote and top narrator Joe Jamason is wonderful to listen to.

Vwry enjoyable conclusion

Possibly the best of the three books in the series. It wraps up the story nicely, and is engaging from beginning to end.

Originality on the future of humanity
