“She'd secretly had a crush on him since they were twelve years old. Last summer, she'd fallen for him hard.”

“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.”

“They had a silent staring contest, but Percy didn’t back down. When he and Annabeth started dating, his mother had drummed it into his head: It’s good manners to walk your date to the door. If that was true, it had to be good manners to walk her to the start of her epic solo death quest.”

“You sneaked into my cabin?”
Annabeth rolled her eyes. “Percy, you’ll be seventeen in two months. You can’t seriously be worried about getting in trouble with Coach Hedge.”
“Uh, have you seen his baseball bat?”
“Besides, Seaweed Brain, I just thought we could take a walk. We haven’t had any time to be together alone. I want to show you something—my favorite place aboard the ship.”
Percy’s pulse was still in overdrive, but it wasn’t from fear of getting in trouble. “Can I, you know, brush my teeth first?”
“You'd better,” Annabeth said. “Because I’m not kissing you until you do. And brush your hair while you’re at it.”
