Tony Danials is seventy-five years old, alone, and carrying one regret he can no longer outrun. He loved Mark for a lifetime but never found the courage to tell him.
Dr. Emily Abrams has spent years developing an experimental process she believes can send a person's consciousness into another reality. Tony will be the first human subject. No one knows where his mind will go, what he'll find there, or whether he'll return unchanged.

Tony has nothing left to lose. He says yes.

He awakens young again in the life he always wanted but never had the courage to claim. Mark is alive. They're together. And for the first time, Tony knows what it feels like to love him without hiding.

But Tony's journey is only the beginning.

David Stevenson later follows him into the same impossible web of parallel lives. His search carries him into 1975, then through realities shaped by love, loss, and roads never taken. In one of those worlds, Mark is alive, but the life David remembers sharing with him never happened. They're only friends.
Then David meets Eric.

What begins as an unexpected connection grows into something neither man was prepared for. But Eric is hiding a secret, and the truth could tear them apart while changing everything David believes about time, reality, and the future he thought he'd lost.
Bound across different worlds, Tony, David, and Eric must face the lives they lived, the choices they feared, and the love they may still have time to claim.
Realities Edge is an emotional journey through parallel worlds and one impossible question.

If you were given a glimpse of the life you never lived, would you have the courage to reach for it?
