“Annabeth laced her fingers through his. In the light of his bronze sword, her face was beautiful.
'We're together,' she reminded him. 'We'll get through this.”

“We don't fit in, you and me," he said. "We're both oddities no one knows what to do with. But we fit together." He took her hand, pressed her palm to his, then laced their fingers through each other's. "We fit.”

“She (Annabeth) put her hand on my spine, and my skin tingled. I (Percy) moved her fingers to the one spot that grounded me to my mortal life. A thousand volts of electricity seemed to arc through my body.”

“Cassie looked up at him, her fingers still intermeshed with his. "Sorry," she said unsteadily. "I was just scared."
"Remind me to get you scared frequently," Nick said. He looked slightly dazed.”

“But she laced her fingers through mine. I remember what she’d told me in New York, about building something permanent, and I thought-just maybe-we were off to a good start.”

“Willie was sound asleep in her lap, but he sucked her little finger. South of Long Beach we stopped at a drugstore and bought a bottle with a nipple, and a bottle of milk. Willie's eyes opened when she put the nipple to his mouth. He fell to his task like a fiend. Camilla lifted her arms high, ran her fingers through her hair, and yawned with pleasure.”

“Annabeth came up to me. She was dressed in black camouflage with her Celestial bronze knife strapped to her arm and her laptop bag slung over her shoulder—ready for stabbing or surfing the Internet, whichever came first.”

“One [nymph], the naiad of the spring, was just emerging from the limpid water as Hylas drew near. And there, with the full moon shining on him from a clear sky, she saw him in all his radiant beauty and alluring grace. Her heart was flooded by desire; she had a struggle to regain her scattered wits. But Hylas now leant over to one side to dip his ewer in; and as soon as the water was gurgling loudly round the ringing bronze she threw her left arm round his neck in her eagerness to kiss his gentle lips. Then with her right hand she drew his elbow down and plunged him in midstream.”

“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.

Percy & Annabeth”

“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.”
