“Nico leaned over the edge o the chasm, thrusting out his hand, but he was much too far away to help. Hazel was yelling for the others, but even if they heard her over the chaos, they'd never make it in time.
Annabeth's leg felt like it was pulling free of her body. Pain washed everything in red. The force of the Underworld tugged at her like dark gravity. She didn't have the strength to fight. She knew she was too far down to be saved.
"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 there!" Percy shouted. "Promise me!"
"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 been 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 oneway trip. A very hard fall.
"As long as we're together," she said.
She heard Nico and Hazel still screaming for help. She saw the sunlight far, far above- maybe the last sunlight she would ever see.
Then Percy let go of his tiny ledge, and together, holding hands, he and Annabeth fell into the endless darkness.”
