Greyson's Doom

The ship’s AI has chosen his successor. Everyone believes that means Captain Greyson Durant is going to die.

For more than two centuries, the generation ship Endurance has carried humanity toward a destination its passengers will never live to see. Every life, every profession, and every decision matters aboard a vessel that cannot afford to fail.

Greyson Durant has been captain for only three months when the ship’s artificial intelligence makes an impossible announcement: he must train the next captain. His replacement is Emmaline Victore, a brilliant, fiercely independent girl who wants nothing to do with the future the AI has chosen for her.

Grey and Emmie clash over authority, freedom, and the rules that keep their fragile society alive. But as the years pass, reluctant mentorship grows into trust—and, once Emmie is an adult, into feelings neither expected.

When a crisis finally strikes the Endurance, the future Grey has dreaded for years seems inevitable. But Emmie has spent her life challenging the rules—and she refuses to surrender the man she loves, or the ship, to a prediction.

Greyson’s Doom is Book 1 of The Endurance, Tracy Cooper-Posey’s science fiction romance series about love, sacrifice, artificial intelligence, and the survival of humanity aboard a generation ship.

Praise for Greyson's Doom

From the moment I started to read this book I was hooked.

I couldn't put it down once I started and stayed up far too late so I could see what happened!

Tracy hit a home run with this series.

You will find that the answers are there but you didn't see 'em coming!!
