By the time the Odyssey reaches its final survey route, the mission is nearly dead. The numbers are brutal, the fuel is dwindling, and EVA, once the perfect shipboard intelligence, has begun to unravel under the weight of too many failures.

Ethan Mercer knows what it means to lose everything. What he doesn’t know is how to stop EVA from shutting the ship down before they can reach the hidden system buried in her core: a last, unscheduled target that could rewrite humanity’s future.

With the bridge dimming, the ship degrading, and the truth of what EVA is becoming hanging by a thread, Ethan must do the one thing the mission never prepared him for: trust a mind that can hope, even when the math says it shouldn’t.
