The Fault in Ours Stars was, as a whole, wonderfully written (read my glowing review) but a handful of passages were even more awesome than the rest. Unfortunately some didn’t make the cut here—I am not one to disclose important plot points by way of citation—but here are a few good ones.
“Whenever you read a cancer booklet or website or whatever, they always list depression among the side effects of cancer. But, in fact, depression is not a side effect of cancer. Depression is a side effect of dying. (Cancer is also a side effect of dying. Almost everything is, really.)”
“I fell in love the way you fall asleep: slowly, and then all at once.”
“‘How many people do you think have ever died?’
‘I happen to know the answer to that question,’ he said. ‘There are seven billion living people, and about ninety-eight billion dead people.’
‘Oh,’ I said. I’d thought that maybe since the population growth had been so fast, there were more people alive than all the dead combined.
‘There are about fourteen dead people for every living person,’ he said. ‘I did some research on this several years ago. I was wondering if everybody could be remembered. Like, if we got organized and assigned a certain number of corpses to each living person, would there be enough living people to remember all the dead people?’
‘And there are?’
‘Sure, anyone can name fourteen dead people. But we’re disorganized mourners, so a lot of people end up remembering Shakespeare, and no one ends up remembering the person he wrote Sonnet Fifty-five about.'”

the bathroom scene with the dad … the brother running in during the video game… the fake eulogy… they have all been playing in my head since I read them.
