The Eternity Protocol: Complete Duology
(2025)(A book in the Cassidy Chronicles series)
An omnibus of novels by Adam Gaffen
The Eternity Protocol DuologyTwo admirals. One crew. One impossible mission to save the future from the past.
Fleet Admiral Kendra Cassidy has spent her life holding the Terran Federation together-through wars, through loss, through the weight of command.
But when a temporal anomaly appears with her name woven into its origins, she faces a truth no one is ready to confront: the timeline itself is coming apart.
Book One: Descent
The crew of the Archer races against time-literally-to stop a cascade failure that could erase centuries of history. To save the Federation, they must dive into the past, where allies can't be trusted, politics turn lethal, and every decision reshapes the future they're trying to preserve.
They'll make deals with the unthinkable. Break rules that define them. And risk becoming the very threat they're fighting to contain.
Because when time becomes the battlefield, there's no such thing as a clean victory.
Book Two: Rebirth
In the aftermath of survival, nothing is the same. The mission is over, but the cost is staggering-and the future they saved may not be the one they recognize.
Now, as the Archer and her crew struggle to find their footing in a fractured reality, Kendra must face what comes after the impossible: rebuilding hope.
Haunted by the choices that saved billions and scarred them all, she leads her family, her fleet, and her Federation through the hardest mission of all-to rediscover who they are.
Because saving the timeline was never the end. It was the beginning of something new.
Across two sweeping novels, The Eternity Protocol delivers a time-bending, emotionally charged science fiction epic that blends the intimacy of found family with the scale of interstellar drama.
It's hopepunk science fiction at its finest-where love, duty, and conviction mean more than firepower, and where even heroes must face the consequences of changing destiny.
