Deep in the forest outside a forgotten town, an abandoned watchtower blinks awake each night, casting a pulse of red light into the trees. When Mara Whitlock stumbles across the signal, she assumes it's a malfunction, a relic of some old fire-lookout system nobody bothered to shut down. But the light isn't broken. It's a message. And somewhere out in the dark, past the tree line, something has finally started answering back. As Mara digs into the tower's history with the help of local outsider Ethan Blackwell and the town's quietly obsessive archivist Daniel Cross, she uncovers a decades-old pact between Blackwater's founders and whatever lives beneath the forest floor. The signal was never meant to summon curiosity seekers. It was meant to keep something asleep. Now that Mara has seen the light, she can't unsee it, and the forest has already marked her as the next name on its list.
