A photograph arrives without a return address. It shows a clearing in the Ohio woods, a ring of stones, and something half-hidden beyond the trees. No explanation. Just five words: Salt Fork. Mid-April. You'll understand.
What begins as observation becomes something else entirely. The woods fall silent. The stones shift. And when one of them steps across a boundary that may not belong to humans, the question isn't what's out there - but whether it's been watching all along.
