I had a sudden urge to get up, a primal need to take in my surroundings and assess the danger—was I in danger?—but the throbbing pain deep in my head made the slightest effort to shift anything seem impossible. Lifting a finger would be too much effort, and I acquiesced, allowing myself to lie still for another few freezing seconds as the frigid water crept over the balls of my feet again. When I blinked my eyes open, I was met by a thick, fuzzy darkness enveloping me like a cloak. Where the hell was I? And wherever it was, what was I doing here?

When I lifted my head a fraction of an inch, I could barely make out anything in front of me. There was hardly a noise, either, nothing but a gentle, steady rumble in the background, and the cry of a bird somewhere in the distance. I made my brain work its way backward—bird, rumble, sand, water—and the quartet formed the vaguely cohesive image of a beach.

Searching for confirmation, I inhaled the salty, humid air deep into my lungs as another slosh of water took aim at my calves. This time the discomfort was enough to push me to my feet, and I wrapped my arms around my naked torso, my sopping board shorts clinging to my goose-bump-covered thighs. An explosion of pain in my head threatened to send me back to my knees, and I swayed gently, wishing I had something to steady myself with, willing my body to stay upright. As I pressed a hand to the side of my skull, I let out a quiet yelp, and felt along a two-inch gash in my scalp. My eyes had adjusted somewhat to the lack of light, and my fingertips were covered in something dark that smelled of rust. Blood. How had I...?

Another low rumble made me turn around, shuffling slowly in a semicircle. The behemoth effort was rewarded by the sight of a thousand glistening waves dancing under the moonlight like diamonds, the water stretching out and disappearing into the darkness beyond. As my ears tuned in to the rhythmic whoosh of the waves, my mind worked hard to process each scrap of information it took in.

I’m definitely on a beach. It’s nighttime. I’m alone. What am I doing here?

Before I could answer the single question, a thousand others crowded my brain, an incessant string of chatter I couldn’t stop or get away from.

Where is everyone? Never mind them, where am I? Have I been here long? How did I get here? Where was I before? Where are my clothes? What day is it?
