The setting sun cast long shadows across the dusty bookshelves of her home office. Elizabeth, perched on a ladder, was attempting to find a specific edition of Jane Eyre. Her search was interrupted by the discovery of a small, leather-bound diary tucked away at the back. It was her own handwriting, from what must have been her early teens. She couldn't help but feel a sudden surge of something wonderful.

She opened the diary, her eyes scanning the faded ink. It seemed she'd been an optimist. "Dear Diary," she read aloud, with a flourish, "Today, I decided to become a pirate. I think I will start by stealing all the cookies..."

A delighted, bubbling sensation began in her chest. She climbed down the ladder and decided to have a biscuit herself.
