The Harvest by Preston Child

When seventeen-year-old Darius McKirk enters the famous Miller Farm corn maze alone, he thinks he's found a way to escape the taunts and bullying of his classmates for a few hours.

But deep within the maze, where fog clings to the stalks and crow-faced scarecrows stand watch, something begins to awaken. Whispering voices drift through the darkness, forgotten paths appear where none should exist, and Darius finds himself confronted by memories he has spent years trying to bury. As the line between reality and nightmare begins to blur, he encounters the restless spirits of those who entered the maze before him and never found their way out.

What waits at the heart of the labyrinth is older than the town itself, a sinister force that has claimed its harvest for generations. As Samhain draws to a close, Darius realizes that some mazes were never meant to be escaped.
