The Plague Forge delivers an unbeatable combination of knockout action and kick-ass characters as the secrets to the ultimate alien mystery from The Darwin Elevator and The Exodus Towers are about to be unraveled.

The hunt is on for the mysterious keys left by the alien Builders. While Skyler’s team of immune scavengers scatters around the disease-ravaged globe in search of the artifacts, Skyler himself finds much more than he expected in the African desert, where he stumbles upon surprising Builder relics—and thousands of bloodthirsty subhumans. From the slums and fortresses of Darwin to the jungles of Brazil and beyond, Skyler and company are in for a wild ride, jam-packed with daunting challenges, run-and-gun adventure, and unexpected betrayals—all in a race against time to finally answer the great questions that have plagued humanity for decades: Who are the Builders, and what do they want with Earth?

Praise for The Darwin Elevator

“A hell of a fun book.”—James S. A. Corey, New York Times bestselling author of Abaddon’s Gate

“[Jason M.] Hough’s first novel combines the rapid-fire action and memorable characters associated with Joss Whedon’s short-lived Firefly TV series with the accessibility and scientific acumen of [James S. A.] Corey’s ‘Expanse’ series.”—Library Journal (starred review)

“The best part about alien stories is their mystery, and Jason Hough understands that like no other. Full of compelling characters and thick with tension, The Darwin Elevator delivers both despair and hope along with a gigantic dose of wonder. It’s a brilliant debut, and Hough can take my money whenever he writes anything from now on.”—Kevin Hearne, New York Times bestselling author of The Iron Druid Chronicles

“Newcomer Hough displays a talent for imaginative plotting and realistic dialogue, and the brisk pacing and cliffhanger ending will keep readers enthralled and eagerly awaiting the next installment.”—Publishers Weekly

“Jason M. Hough does a great job with this huge story. The world of Darwin and the Elevator is deliciously complex and satisfying.
