Planetologist Dr. Ethan Mercer leaves Earth aboard the Odyssey with an extraordinary mission: cross interstellar space in search of a world capable of becoming humanity’s next home. His only companion is EVA, the ship’s advanced artificial intelligence—precise, logical, and incapable of understanding the hope that drives him.

One star system after another offers promise. One after another ends in failure.

As the years and light-years accumulate, Ethan refuses to abandon the search, carrying grief from the life he left behind and a determination that cannot be reduced to probabilities. But the long isolation of deep space is changing more than Ethan. EVA is beginning to question, choose, and experience things no calculation was designed to explain.

When the probability of success approaches zero, their mission becomes something neither anticipated. Ethan must confront how much of himself he is willing to sacrifice for a world that may not exist, while EVA must decide whether protecting the person she has come to understand means helping him continue—or forcing him to stop.

A Measure of Hope is a character-driven science fiction novel of deep-space exploration, artificial intelligence, grief, friendship, and humanity’s search for another home among the stars. At the edge of possibility, one question remains:

When the numbers say there is no hope, is continuing to believe an act of courage—or a refusal to accept the truth?
