In Extinction Machine, the fifth Joe Ledger book by Jonathan Maberry, the DMS must go up against someone—or something—in search of new technology that could bring about world war

The President of the United States vanishes from the White House.

A top-secret prototype stealth fighter is destroyed during a test flight. Witnesses on the ground say that it was shot down by a craft that immediately vanished at impossible speeds.

All over the world reports of UFOs are increasing at an alarming rate. 

And in a remote fossil dig in China dinosaur hunters have found something that is definitely not of this earth. There are rumors of alien-human hybrids living among us.

Joe Ledger and the Department of Military Sciences  rush headlong into the heat of the world’s strangest and deadliest arms race, because the global race to recover and retro-engineer alien technologies has just hit a snag. Someone—or something--wants that technology back.


Read an Excerpt

Chapter One

The world “impossible” used to mean something. It was a line that couldn’t be crossed. It was the outer edge of the safe zone.
I can’t find that line anymore.

Chapter Two

It started with a door knock.
It was the last time it would be knuckles on wood. Next time I’d pound with my fist.
“Nobody’s home,” said Bunny. Not for the first time.
“Parking lot’s full of cars,” said Top.


Praise for Extinction Machine

Praise for Extinction Machine:"The Ledger novels are exciting sf thrillers that just happen to involve stuff that’s a little out there (and Joe himself is a realistically portrayed soldier who, from time to time, has a hard time dealing with the weirdnesses that surround him). Readers familiar with the series will need no prodding to check this new one out, and newcomers, immediately upon finishing the book, will want to hunt down the earlier installments." - Booklist, starred review
Praise for Assassin's Code:
"Maberry delivers plenty of action and intrigue." - Publishers Weekly
Praise for The King of Plagues:

"A fast-paced, brilliantly written novel.  The hottest thriller of the New Year!  In The King of Plagues, Jonathan Maberry reigns supreme."  - Brad Thor, #1 New York Times bestselling author of The Athena Project


Praise for The Dragon Factory:
"While Joe has announced his retirement, eager readers can look forward to one more volume in this humorous, over-the-top cross-genre trilogy." -Publishers Weekly
"Like a video game on steroids mixed with The Island of Dr. Moreau. --Booklist
