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.

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.

Could not put it down

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

Outstanding..

Outstanding.. although slightly less so than 1&2. Just has some holes and improbable gaps that had to be bridged. A few deus ex machina moments like when the 3 of them land secretly in the gigantic secret guard corp base, in the exact spot where they could amazingly overhear the 3 most senior supporting antagonists discuss their entire plan, outloud, as though it was the first time they'd ever put voice to and summarized it. What an amazing stroke of luck! I actually had to re-listen to several chapters, several times over, just to make sure I hadn't missed or misunderstood something as the story passed over these leaps of logic.
Anyway... The alien rebels' computers and a couple other features made book 3 much much less of a hard sci-fi feel than 1 & 2 had been, and more of a sci-fi fantasy. Still, overall outstanding and a full conclusion to the series.

Great story here!

the story was awesome, and the scifi ideas and concepts were unique and well thought out! my only complaint is that the end felt rushed, the main antagonist just seemed to go away.. and I would have liked more info regarding one specific moment.. but I don't want to spoil anything so I'll leave it there. enjoy!
