Two admirals. One crew. One impossible mission to save the future from the past.

Fleet Admiral Kendra Cassidy once rewrote the rules of war, peace, and civilization itself. With her wife, Aiyana, she fought the Artemis War. Built the Terran Federation. Proved that humanity could rise above its worst instincts.

But now?

She's back in uniform. Back in the fight. And the future she built is on the edge of collapse.

A new temporal anomaly has emerged—one that shouldn't exist, one tied to Kendra herself. It's a cascade event that threatens to destabilize everything the Federation holds dear. So Kendra, her wives, and the crew of the Dreamer are pulled in—dragged into a black-ops mission of historical sabotage, high-stakes diplomacy, and brutal tradecraft.

They'll cross borders that shouldn't exist. Break rules that aren't supposed to bend. And meet beings who have watched the rise and fall of civilizations with folded arms.

But time travel never plays fair. And every move they make changes the board.

From tense Federation briefings to desperate deals with crewmembers with extraordinary abilities, from ancient quantum archives to a deadly infiltration of a rogue lab, Kendra fights to do what's right. But in the shadows of the past, ethics become luxuries. And when push comes to shove, the mission demands blood.

She orders the impossible. She crosses lines she swore never to touch.
And somewhere along the way, she forgets where the line is between survival and surrender.

Descent is the explosive first half of The Eternity Protocol duology—an emotionally charged, time-twisting sci-fi epic about what happens when the hero you need has already been broken by the job.
