Tomorrow and Tomorrow and Tomorrow by Gabrielle Zevin.

“T and T and T is a beautifully wrought saga of human connection and the creative process, of love and all of its complicated levels. A gem of a novel, intimate yet sweeping, modern yet timeless. Bits of this book lingered in my head the way ghosts of Tetris pieces continue to fall into your mind’s eye after playing.” -Erin Morgenstern, author of The Starless Ses
