Here's a potential idea for a horror short story involving boys:

Title: The Lost Boys of Raven's Peak

Plot Idea:

A group of friends, all boys around 12-13 years old, embark on a camping trip to Raven's Peak, a remote and notorious location rumored to be haunted. As they explore the woods, they stumble upon an ancient, mysterious symbol etched into the bark of a tree. Unbeknownst to them, this symbol unleashes a malevolent entity that begins to manipulate and terrorize the boys, forcing them to confront their darkest fears.

Themes:

- The struggle for survival and camaraderie among the boys

- The blurred lines between reality and the supernatural

- The vulnerability of adolescence and the horrors of growing up

Twist:

As the story unfolds, it becomes clear that one of the boys has a dark secret, and the entity is exploiting this secret to wreak havoc on the group. The boys must confront their own demons and work together to survive the night and uncover the truth behind the haunting.

Ending:

The story concludes with a chilling twist: the boys who survive the night are forever changed, and the entity's influence continues to haunt them long after they leave Raven's Peak. The symbol, now a constant reminder of their terror, becomes a harbinger of doom for anyone who dares to venture near the accursed place.
