“Frank heard a laugh behind him. He glanced back and couldn't believe what he saw. Nico di Angelo was actually smiling.

"That's more like it," Nico said. "Let's turn this tide!”

“No," Frank said. "I'm only a centurion."

Jason cursed in Latin. "He means he can't control a whole legion. He's not of high enough rank."

Nico swung back his black sword at another gryphon. "Well, then, promote him!”

“Cupid said, smashing another skeleton to pieces."Nico," Jason managed to say, "it's okay. I get it."

Nico glanced over, pain and misery washing across his face.

"No you don't," he said. "There's no way you can understand."Cupid chided.”

“Frank gave Leo a confused smile- like he couldn't decide whether to gloat or to thank Leo for being a doofus- but he cheerfully let Hazel drag him along.”

“Nico drew his sword. His smile was even more unsettling than his scowl.

"Underground," he said. "My favorite place."

Underground wasJason's favorite place.”

“Grover and Nico came back from their walk, and Grover helped me fix up my wounded arm.
"It's green!" Nico said with delight.”

“Percy, let me go" she croaked. "You can't pull me up."
His face was white with effort. She could see in his eyes that he knew it was hopeless.
"Never," he said. He looked up at Nico, fifteen feet above.
"The other side, Nico! We'll see you there. Understand?"
Nico's eyes widened. "But-"
"Lead them!" Percy shouted. "Promise me!"
"I-I will."
Below them, the voice laughed in the darkness. Sacrifices. Beautiful sacrifices to wake the goddess.
Percy tightened his grip on Annabeth's wrist. His face was gaunt, scraped and bloody, his hair dusted with cobwebs, but when he locked eyes with her, she thought he had never looked more handsome.
"We're staying together," he promised. "You're not getting away from me. Never again."
Only then did she understand what would happen. A one-way trip. A very hard fall.
"As long as we're together," she said.
She heard Nico and Hazel still screaming for help. She saw sunlight far, far above- maybe the last sunlight she would ever see.
Then Percy let go of his ledge, and together, holding hands, he and Annabeth fell into the endless darkness.”

“…He is driven by bitterness and anger. You can understand that.’
Nico wanted to yell, Like you know what I feel?”

“Tyson, Frank is a descendant of Poseidon."
"Brother!" Tyson crushed Frank in a hug.
Percy stifled a laugh. "Actually he's more like a great-great-… Oh, never mind. Yeah, he's your brother."
"Thanks." Frank mumbled through a mouthful of flannel.”

“Oh, God," I said.
"No, it's Dexter," he replied, offering me his hand, which I ignored.
He glanced behind him, then back at me. "I'll see you soon," he said, and grinned at
me.
"Like hell," I replied”
