Annihilation [Chapter One]
Four scientists begin exploring a sinister wilderness.
"We were on a dirt trail strewn with pebbles, dead leaves, and pine needles damp to the touch. Velvet ants and tiny emerald beetles crawled over them. The tall pines, with their scaly ridges of bark, rose on both sides, and the shadows of flying birds conjured lines between them. The air was so fresh it buffeted the lungs and we strained to breathe for a few seconds, mostly from surprise. Then, after marking our location with a piece of red cloth tied to a tree, we began to walk forward, into the unknown. If the psychologist somehow became incapacitated and could not lead us across at the end of our mission, we had been told to return to await 'extraction.' No one ever explained what form 'extraction' might take, but the implication was that our superiors could observe the extraction point from afar, even though it was inside the border."
