Tachyon Tunnel 4

With 15 literary awards, from the #1 bestselling series, Tachyon Tunnel 4 delivers a masterful blend of cutting-edge science, high-stakes adventure, and powerful human connection.

Humanity has crossed the threshold of impossible. With tachyon tunnel technology now unlocking instantaneous travel across space and time, Alex Durant and his allies have pushed civilization to the brink of a Kardashev Type II future, harnessing the energy of stars, reshaping planets, and rewriting the limits of physics itself. But as power expands, so do the consequences.

In the aftermath of devastating conflict with the Daklin Empire, a deeper truth begins to surface, one hidden not just across galaxies, but across millions of years of carefully orchestrated history.

At the center of that truth lies Eidolon, a Type II+ civilization established in the remote Large Magellanic Cloud. Eidolon was established at the beginning of the Daklin reign by a race intent on preserving civilization from the destructive influence of the Empire. It is a civilization far beyond the Daklin technological horizon, bound by ancient rules designed to prevent its own destruction. Eidolon holds secrets so profound it could either secure humanity's future… or end it.

As Alex and his team are drawn into Eidolon's inner workings, they uncover a system built on extraordinary achievement, and dangerous restraint. While humanity races forward, eager to expand, explore, and defend itself, Eidolon has chosen a different path: isolation, control, and the suppression of forces it deems too risky to unleash.

Caught between competing visions of the future, one of limitless expansion, the other of enforced equilibrium, Alex must confront a question far more significant than any enemy fleet: Should humanity become everything it is capable of… even if it risks transforming into the very thing it fears?

As new alliances form, hidden histories unravel, and technologies emerge that challenge the nature of reality itself, the line between salvation and catastrophe begins to blur.

Because in a universe where time is no longer a constraint… the greatest threat may not be what comes next, but what has already been set in motion.
