"You're asking me to define an abstract concept that no one has managed to explain since time began. You sort of sprang it on me," Gansey said. "Why do we breathe air? Because we love air? Because we don't want to suffocate. Why do we eat? Because we don't want to starve. How do I know I love her? Because I can sleep after I talk to her. Why?"

“A secret is a strange thing. There are three kinds of secrets. One is the sort everyone knows about, the sort you need at least two people for. One to keep it. One to never know. The second is a harder kind of secret: one you keep from yourself. Every day, thousands of confessions are kept from their would-be confessors, none of these people knowing that their never-admitted secrets all boil down to the same three words: I am afraid. And then there is the third kind of secret, the most hidden kind. A secret no one knows about. Perhaps it was known once, but was taken to the grave. Or maybe it is a useless mystery, arcane and lonely, unfound because no one ever looked for it. Sometimes, some rare times, a secret stays undiscovered because it is something too big for the mind to hold. It is too strange, too vast, too terrifying to contemplate. All of us have secrets in our lives. We’re keepers or keptfrom, players or played. Secrets and cockroaches — that’s what will be left at the end of it all.”

“His feelings for Adam were an oil spill; he'd let them overflow and now there wasn't a damn place in the ocean that wouldn't catch fire if he dropped a match.”

“His eyes were frighteningly alive, the curve of his mouth savage and pleased. It suddenly didn't seem at all surprising that he should be able to pull things from his dreams. In that moment, Blue was a little in love with all of them. Their magic. Their quest. Their awfulness and strangeness. Her raven boys.”

“As they moved through the old barn, Adam felt Ronan's eyes glance off him and away, his disinterest practised but incomplete. Adam wondered if anyone else noticed. Part of him wished they did and immediately felt bad, because it was vanity, really: See, Adam Parrish is wantable, worthy of a crush, not just by anyone, someone like Ronan, who could want Gansey or anyone else and chose Adam for his hungry eyes”

“Gansey had once told Adam that he was afraid most people didn't know how to handle Ronan. What he meant by this was that he was worried that one day someone would fall on Ronan and cut themselves.”
