The afternoon sun streamed through the bookstore window, illuminating dust motes dancing in the air. Sarah skipped down the aisles, the sheer joy of being surrounded by books making her feel weightless. She needed a new escape, a world to lose herself in.

She chose a thick volume, its cover faded and worn, and carried it to a small, secluded table. She opened the book with anticipation, tracing the worn edges of the pages. A tickle in her stomach told her this book was something special.

Suddenly, a small, folded paper slipped out from between the pages. "Ooh!" she gasped, her eyes widening. She carefully unfolded it, excitement bubbling up inside her.
