At eight years old, Dora Culligan's world shattered the night her brother Tommy died. Her family called it suicide. They told her to move on. Forget. But at fourteen, Dora can't forget. Shards of memory cut through her-blood, screams, a gun she shouldn't have seen. Every time she grasps for the truth, her family tightens the story, rewriting her past until she doubts her own mind. Was Tommy's death what they said it was-or something far more dangerous? Trigger is a haunting psychological thriller about memory, manipulation, and the devastating lies families tell to survive.
