" Ronan’s expression was still incendiary. His code of honor left no room for infidelity, for casual relationships. It wasn’t that he didn’t condone them; he couldn’t understand them. “So he’s a man-whore. It’s not your problem,” Gansey said. Ronan was not really Gansey’s problem, either, in Adam’s opinion, but they’d had this argument before. One of Ronan’s eyebrows was raised, sharp as a razor. Gansey strapped his journal closed. “That doesn’t work on me. She had nothing to do with you and Declan.” He said you and Declan like it was a physical object, something you could pick up and look underneath. “You treated her badly. You made the rest of us look bad.” Ronan looked chastened, but Adam knew better. Ronan wasn’t sorry for his behavior; he was only sorry that Gansey had been there to see him. What lived between the Lynch brothers was dark enough to hide anyone else’s feelings. "
