Detective Byron Constantine wakes with a plan.

Today, he will follow the final clues in his investigation into Circe, a criminal organization that’s eluded him for months. He knows where to go. He knows who to see. Everything is finally falling into place.

Except… something is wrong.

The injuries on his body don’t make sense. People recognize him when he doesn’t remember them. And when he glances at a newspaper over breakfast, Byron realizes the date is impossible.

It isn’t February 1884. It’s October 1888.

The leaves are turning.
The city has moved on.
And the life he remembers no longer exists.

As small inconsistencies spiral into a terrifying truth, Byron must confront the possibility that the greatest mystery he’s ever faced isn’t Circe at all—but himself.
