The musty air hit Amelia like a physical blow as she pushed the heavy bookcase aside. The scent – old paper and something like dried violets – instantly transported her. Years peeled away, and she was suddenly a child again, nose pressed against her grandmother's floral wallpaper, breathing in the same, comforting aromas. She ran a hand along the rough brick of the hidden room's wall, feeling a shiver of recognition. It felt like the secret hideaway she’d always craved, a space out of time.
