Locked In

When seventeen-year-old Mia Jensen arrives at school expecting a typical Thursday, the last thing she anticipates is a full lockdown. Sirens blare, teachers panic, and the school descends into chaos. But when the emergency persists and no one comes to explain, Mia and a small group of students realize something darker is at play. As the night drags on, strange things begin to happen-hallway lights flicker, notes appear, and doors lock and unlock at random. Then, one student goes missing. Another is found unconscious. Mia, a puzzle-solving prodigy, begins to suspect that the lockdown is a cover for something much more sinister. Using hidden clues and ciphers, she unravels a trail that leads to a forgotten scandal, a security guard with a dangerous past, and a fellow student who knows more than they're admitting. When the truth explodes, Mia is left to navigate betrayal, trauma, and a final game that could cost her everything. Locked In is a high-stakes psychological mystery filled with plot twists, heart-pounding suspense, and a resilient heroine who refuses to be silenced.

About the Author :
When I first began writing The Graveyard Secret, I didn't set out to create a trilogy. I only had a single, haunting image in my mind-an old elm tree standing watch over a graveyard, and the feeling that beneath its branches, a truth waited to be found. The story unfolded slowly, like uncovering something buried. Each chapter revealed not just plot, but pieces of the people who lived within it-Mary Dicks, her silences, her strength, and the shadows that shaped her. I realised early on that while there was mystery in the pages, the real heart of this book was about family-the ties we protect, the secrets we keep, and the echoes they leave behind. As I wrote, the story began to stretch beyond one book. Mary's past whispered to me, demanding its own voice, and thus The House on Bramble Street was born. And in the other direction, her sons, Damian and Daniel, carried the legacy forward into Whispers Beneath the Elm. What started as one story became a tapestry of three lives, three timelines, and one shared truth: some secrets never rest. Writing these books has been a journey of patience, discovery, and deep connection. I've written through moments of creative flow that felt unstoppable, and moments of silence where the words hid from me. Both were part of the process, teaching me to listen-to the story, to the characters, and to my own persistence. This trilogy belongs to the readers as much as it does to me. You've walked the graveyards, sat under the elm, and turned over the same questions I did while writing: What do we owe the truth? And what is the cost of uncovering it? Thank you for taking this journey with me. - Kim Möller
