I couldn’t be far, but the river covered everything under a blanket of deep, frenzied rapids that wound over the land in both directions. Debris rolled past me, floating up and down on the waves, as if all the animals on the merry-go-round had been set free. I looked for some clue, something, anything breaching the surface to let me find her. A tire. A fender. The car was near me, trapped under the water along with my wife, but there was nothing to tell me where she was.

I stood there, needing help. Please!

That was when the Many Worlds sent me . . . myself.

Dylan Moran burst from the river right in front of me. We weren’t even ten feet apart. He rose up like a sea creature, covered in mud and slime, spitting out water and gasping for breath. It was déjà vu in reverse. I was him. He was me. This was the moment when it had all started, but now we’d changed places.

He was in the water, and I was the man on the riverbank.

When the lightning flashed again, Dylan spotted me across the surging flood. It took a moment for him to register what he was seeing. I knew the feeling, because I’d already been through it. His face twisted with confusion, just the way mine had, because the man on the riverbank couldn’t be real. But I was.

“Help me!” he shouted. My words.

The lightning faded to darkness, and he called out again: “My wife is drowning! Help me find her!”

Then he was gone, diving down into the water. With a kick of his feet, Dylan disappeared, but I knew he wouldn’t find Karly. I’d been where he was, and I’d failed. He would search and search and come up empty. He would swim into nothingness. He would swim into other worlds.

Saving her was up to me now.

I waded into the water, where the wild current knocked me sideways. My feet spilled out on the slippery ground beneath me. I landed hard on my back, and the river sucked me into a whirlpool before I even took a breath. In an instant, the rapids spun me downstream in crazy circles. I choked, rising and falling, and finally, I fought back to the surface, where I gagged out water and desperately inhaled. The river swept against me like a speeding truck, but I kicked furiously with my hands and feet to fight the flow and stay where I was.

The car had to be submerged close by, but I couldn’t see it. Once I was down below, I would be swimming blind. I was running out of time. I only had one last chance.
