Liam ran his fingers over the worn cover of the book, feeling the familiar texture against his skin. He had to replace it. He'd been looking back at the past, the memories of a life that felt a million years ago. He found himself remembering the comfort of childhood. He'd been messaging "StoryTeller," an online friend. They'd bonded on a forum dedicated to classic literature. They shared stories, sharing a love of books.

"StoryTeller" had mentioned a used bookstore in the city, the one where Liam used to spend hours as a child. The memories were flooding back. He knew it well. He was surprised he hadn't gone back.

Liam decided to go. He walked through the door, and smelled the scent of old paper. He found her, browsing the shelves.
