Not every limit is a flaw.
Caleb believes every problem has a solution. He's never once asked whether they should be solved.
Years ago, Elaina drew him into the study of cognitive decay. Now Caleb's own mind is betraying him, dividing memory into rival versions of the truth.
Elaina begs him to accept treatment before there's nothing left of him to save. Instead, he traces the decay to its source. Then he learns how to stop it, not just in himself, but in anyone.
Aging stops, death retreats, and what began as Caleb's salvation becomes everyone's. But eternity has a price no one agreed to pay: a future measured in lives that will never begin.
Caleb alone decides what the future can afford to lose.
