Nico raised his eyebrows. "Do you?”

“Hey, check this weirdo out." Hi was inspecting a bust on the mantel. "This face is ninety percent eyebrow. What do you want to bet he owned slaves?"

“So,’ Nico said, ‘since we’re going to be spending at least a year seeing each other at camp, I think I should clear the air.’ Percy’s smile wavered. ‘What do you mean?”

"That Valentine might have drowned?"
