Looking for Miriam — Kristine Kathryn Rusch

Ben knows Miriam exists, even if his shrink insists he'll never find her. Ben must let her go, the shrink says, if he hopes to recover from his injury. Still, he looks everywhere, until one day a memory of where she works comes back to him.

But just when Ben thinks he has found Miriam at last, he gets a glimpse at just how much he has actually lost.
