When you read a book, it is a story within the story. The French call this mise-en-abîm: the condition of being between two mirrors with an abyss of yous staring back.

…

You turn the page of the fictional story while an hour of your own passes. The characters breathe, laugh and cry, and so do you. When you finish their tale, you close the book and set it aside, dreaming of their ever-after, while stepping out into yours. But you don’t leave the story as you found it. No, it’s forever changed. The evidence is there: a chocolate smudge, a tea stain, beach sand, dandelion spores, a stray hair, a note, a name, a message. The story has been splintered into a duplicate image, a reflection of you in bits between the pages.
