The scent of old books and parchment embraced Eliza as she entered the library, a place that always brought her a sense of peace. That peacefulness, of late, had taken on an extra layer, something light and effervescent. A librarian approached, holding a book, its cover displaying an image of her reading amongst the shelves. The title read, "The Librarian's Legacy: A Life of Stories." It was an overview of her life. She grinned, a feeling of wonder and thrill bubbling inside her, ready to burst forth with excitement. She felt like she wanted to stay in the library all day.
