'The Big Book'

Basically, a place to collect shorter stories and/or oneshots.

While walking around the book store, you come upon a large book. One so big, you're pretty certain that it's almost impossible to move said book.

"Oh yes. That." Lily explained, she and Rose making her way over. "That's a collection of short stories and oneshots that updates from time-to-time."

You give a nod.

"You're free to give it a look."

Complying with their instructions, you pull the the book open and began to look through your options.
