The Signal: Signal Series Book Two, part of The Great Silence Universe - Paperback

They listened.
Now they must decide what to do with what they've heard.

When the message is finally decoded, it becomes clear that the signal did not come from the stars - but from a lost human colony, long believed to be gone. On the frozen world of Honora, a small group of survivors has endured in isolation, unaware that anyone would ever hear their plea.

As plans are made to reach them, Lieutenant Commander Jo Willis must confront the limits of Terran knowledge, responsibility, and preparedness. What was once an abstract mystery becomes a human reckoning: survival shaped by choices made generations ago, and the consequences of policies meant to protect a civilization that turned inward too quickly.

Meanwhile, on Tau Station, the androids who first carried the signal forward are no longer simply caretakers. As they take on new roles beyond their original design, questions of autonomy, duty, and moral agency begin to surface - not as rebellion, but as necessity.

The Signal is a quiet, emotionally grounded science fiction novel about distance, responsibility, and the cost of listening when the answer is not simple. It continues the story begun in Tau Station, expanding the Great Silence universe into its human heart.
