A class trip they’ll never forget… if they survive it.
Chelsea has everything a modern teen dreams of—friends, good grades, and a future full of possibilities. But when she finds her mother’s hidden diary, she learns a secret that shatters her the man she calls Dad isn’t her father… and the truth is far more dangerous.
As her class heads to the Hill Country to explore a notorious bat cave, Chelsea can’t shake the feeling she’s being watched. And she’s right. Someone connected to her mother’s past has followed her—someone who’s waited years for revenge.
When students begin to vanish in the dark tunnels and the trip turns into a real-life horror movie, Chelsea must confront the sins of the past before they become her own undoing.
But every killer has a story. Every victim has a choice.
