Humanity’s Judgment Begins Now

In 2175, humanity has conquered scarcity, colonized the solar system, and mastered technologies once thought impossible. Then, something unexpected emerges from the edges of space.

The object is enormous, ten-sided, and older than anything humanity can comprehend. Dubbed the Decahedron, it takes position near Saturn and humankind does what it has always done when confronted by the unknown: studies it, speaks to it, and prepares to fight it. But every attempt to understand the object brings consequences, and every response only intensifies the threat.

On Earth, a widowed Princeton University linguist named Julian Wexler receives a visitor. Calling himself Virgil, the mysterious stranger knows what the Decahedron is and what has happened to those who have encountered it before. Virgil believes Julian may be humanity’s best hope of surviving what comes next.

Because the Decahedron has not come to invade. It has come to judge.

For fans of Cixin Liu’s The Three-Body Problem, Decahedron is a thoughtful, speculative debut centered on first contact with an enigmatic ancient intelligence and the question of whether aggression or humility will determine humanity’s survival.
