Catalyst Gate

By: Megan E. O'Keefe

Narrated by: Joe Jameson

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 in the final book of this explosive Philip K. Dick award nominated space opera.
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

"Meticulously plotted, edge-of-your-seat space opera with a soul; a highly promising science-fiction debut."—Kirkus on Velocity Weapon

"Velocity Weapon is a spectacular epic of survival, full of triumph and gut-wrenching loss."—Alex White, author of The Salvagers Series

"Velocity Weapon is a roller-coaster ride of pure delight. Furious action sequences, funny dialog, and touching family interactions all wrapped up in a plot that will keep you guessing every step of the way. This is one of the best science fiction novels of 2019."—K. B. Wagers, author of the Indranan War Trilogy

"O'Keefe delivers a complicated, thoughtful tale that skillfully interweaves intrigue, action, and strong characterization. Themes of found family, emotional connection, and identity run throughout, backed up by strong worldbuilding and a tense narrative. This series opener leaves multiple plot threads open for further development, and readers will look forward to the next installments."—Publishers Weekly on Velocity Weapon

"Full of twists, feints, and deception, O'Keefe's latest presents a visionary world rife with political intrigue and space adventure."—Booklist (starred review) on Velocity Weapon

"Velocity Weapon is fast-paced, twisty, edge-of-your-seat fun. Space opera fans are in for a massive treat!"—Marina J. Lostetter, author of Noumenon

Very good chapter in the series

I thoroughly enjoyed this book in the series. My only complaint is the language used to get the point across. it seems now days people find it necessary to use that language too frequently. other than that, I highly recommend this series.

Loved all 60 hours of this series!

Great hard sci-fi. O’Keefe masterfully spins a web of characters and tech that feels like a real place. Joe Jamison brings it to life with superb narration.

Amazing story and masterful narration.

It does not get any better than this. The narrator can create so many different voices it’s utterly convincing. The story had me at the edge of my seat and not wanting to leave.

Could not put it down

Attention to detail masterful written Except for the sexual content one of the better books I listened to

Amazing

loved the final book, and still wanting more from it. I want to read again, far in the future, what is Sanda and Thomas and Bero are up to and what new adventures they will have
