No Man Is An Island; Every Book Is A World. - Gabrielle Zevin

Every book is a world.

They had the rare kind of friendship that allowed for a great deal of privacy within it. One of the reasons they had become such good friends originally was because she had not insisted he tell his sad stories to satisfy her own curiosity. The least he could do was return the favor.

The words you can't find, you borrow.
We read to know we're not alone. We read because we are alone. We read and we are not alone. We are not alone.
My life is in these books, he wants to tell her. Read these and know my heart.
We are not quite novels.
The analogy he is looking for is almost there.
We are not quite short stories. At this point, his life is seeming closest to that.
In the end, we are collected works.

Every book is a world.
