The small, cluttered apartment felt spacious and bright, lit by the sheer energy coursing through Amelia's veins. The air in her lungs felt crisp and cool, even though the room was stifling with the scent of old paper. She had been tasked with organizing her late aunt’s belongings. She had expected to be saddened, but the exact opposite was happening.

She found the letter tucked between the pages of a forgotten scrapbook. The letter, her aunt's resignation, sang to her, a song of boldness and self-discovery. Amelia felt a surge of adrenaline, and a giggle escaped her lips.

She grabbed her phone to call her cousin. The world felt open and waiting.
