“Finally!” Maya exclaimed, holding up the book. She’d been searching for this specific edition of “Little Women” for months. The librarian recommended the second-hand shop around the corner, and she'd been right. She felt fantastic.

She sat on the floor, surrounded by her collection of books. As she opened the cover of the new find, a dried leaf fluttered out. A small piece of paper was attached.

The note on the paper was filled with loving advice. A warmth spread through her, a sense of connection to someone she'd never met. She closed her eyes, savoring the moment. A peaceful feeling settled over her.
