" Molecules never die, I thought. Hadn’t they told us that in chemistry? Hadn’t they said a molecule of Julius Caesar’s dying breath was, statistically speaking, in every breath we took? Same with Lincoln. Or our grandparents. Molecules exchanging and mingling, on and on. Particles that had once been others and now moved through us. “Evie!” said Jack. “Look! I found a sand dollar!” That was the sad thing about my molecules: they wouldn’t remember him. "
