Stargate meets Aliens in this explosive near-future sci-fi thriller from New York Times bestselling authors Andrews & Wilson.

When DARPA builds the ultimate tactical weapon—a portal capable of instant travel across any distance—they recruit Marine Raider Captain Jackson Glover and his elite team to test it. But this isn’t just a new form of transport: it’s Pandora’s Box.

Every time the portal opens, the team must pass through Other Earths—alternate realities filled with hostile environments, alien ecosystems, and threats that defy human comprehension. What should be a shortcut through space becomes a gauntlet of survival, where each “layover” could unleash horrors capable of annihilating our world.

For Glover, every jump is a spin of the cosmic revolver—a high-stakes game of interdimensional Russian Roulette with the fate of humanity in the balance.
