Kay Carter knows something is wrong the moment she wakes up.
Her calendar says October 31st. Her memory says October 13th. And everyone around her insists nothing has changed at all.
But the world doesn't stay consistent for long.
Her younger brother Ray begins slipping in and out of moments he can't explain-missing time, fractured memories, and quiet gaps in his own awareness that seem to leave subtle changes behind.
As Kay tries to hold onto what she knows is real, she and her friends are drawn into the mystery of Lucks Lake, a place tied to warnings from a fortune teller who claims someone close to them has already been affected.When one of them tests the lake and returns unchanged, the answers they were searching for only multiply.
Because nothing is matching anymore.
As Ray's experiences deepen, Kay is forced to confront the possibility that some truths don't arrive cleanly-and that understanding what is happening may come at the cost of everything she thought she could trust.
October 13th is a psychological thriller about perception, memory, and what happens when reality stops agreeing with itself.
Not time. Not memory. Not even themselves.
