“Liesl knew then that Po had been lying. The ghost did miss the living side. She understood then, too, that everyone drowns differently; and that for everyone, even ghosts, there is a different kind of air.”

“She understood then, too, that everyone drowns differently and that for everyone - even ghosts - there is a different kind of air. Chapter 15”

“Po swirled upward from where it had been sitting, and floated over to the window. "When you go swimming and you put your head under the water," Po said, "and everything is strange and underwater-sounding, and strange and underwater-looking, you don't miss the air do you? You don't miss the above-water sounds and the above-water look. It's just different." "True." Liesl was quiet for a moment. Then she added, "But I bet you'd miss it if you were drowning. I bet you'd really miss the air then.”

“Are you a girl or a boy?' Liesl was wearing the same thin nightshirt she had been wearing since Tuesday, when her father died, and it occurred to her that if the ghost was a boy, she should cover up. 'Neither,' the ghost replied.Liesel was startled. 'You have to be one or the other.''I don't have to be anything,' the ghost replied, sounding irritated. 'I am what I am and that's all. Things are different on the Other Side, you know. Things are... blurrier.”

“Of all the miracles Po had seen in the time and space of its death, Po thought this--the absorption of another, the carrying of it--was the most bewildering and remarkable of all. Whenever Bundle separated again, Po was left with an ache of sadness that reminded the ghost of the body it had left behind.”

“Po flickered. "Thank you?" it repeated. "What is that?"Liesl thought. "It means, You were wonderful," she said. "It means, I couldn't have done it without you.”

“Additionally, Liesl and Po is the embodiment of what writing has always been for me at its purest and most basic--not a paycheck, certainly; not an idea, even; and not an escape. Actually, it is the opposite of an escape; it is a way back in, a way to enter and make sense of a world that occasionally seems harsh and terrible and mystifying.
